I'd bet for 'B':

Premise 1: One of the limiting factors in human physical performance is the amount of oxygen
that is absorbed by the muscles
from the bloodstream.
Premise 2: ...entrepreneurs have begun selling bottles of drinking water, labeled
“SuperOXY,” that has extra oxygen dissolved in the water
Premise 3: the only way to get oxygen into the bloodstream so that it can be absorbed by the muscles is
through the lungs =>
Conclusion: Such water ("SuperOXY") would be useless in improving physical performance

improving physical performance = get rid of the limiting factors
1 of the limiting factors = quantity of oxygen that is absorbed by the muscles (from premise 1)
Assumption: to drink "SuperOXY" = to provide oxygen to the muscles = improve physical performance
Premise 3 destroys such assumption and provides evidence for the conclusion

'B' also destroys such assumption and provides evidence for the conclusion because the fact that "amount of oxygen in the blood of people who are exercising is already more than the muscle can absorb" makes any additional oxygen unnecessary and as a consequence makes "SuperOXY" useless in improving physical performance

'A' on the other hand actually is out of scope because we don't know whether the fact that "the water lost in exercising can be replaced with ordinary tap water" makes "SuperOXY" useless in improving physical performance. :wink:

Well, guys, I see this question makes a lot of discussion. On gmatclub there are several older posts with this CRQ.
I picked answer B. And I am confident taht this is the right answer. Why? After surfing the Internet, I managed to find this question on Manhattan GMAT web-site. The OA there is the C, but if you analyze better all the answer choices and question stem, you can see that answer B (in this post on GMATclub) is RIGHT!.
Because on MGMAT the answer choices are given in reverse order. Look attentively. The relationship is the same: "the amount of oxygen in the blood who is exercising already more than the muscles can absorb" is mentioned in the stem and "the only way to get oxygen into the bloodstream so that it can be absorbed by the muscles is through the lungs" is mentioned in the OA.THUS B

What is the source for A?

I agree with B too.

Is there an official explanation?

Definitely B.

Below is the same question from MGMAT but w/ reverse of our choice B with the original statement.

One of the limiting factors in human physical performance is the amount of oxygen that is absorbed by the muscles from the bloodstream. Accordingly, entrepreneurs have begun selling at gymnasiums and health club bottles of drinking water, labeled "SuperOXY," that has extra oxygen dissolved in the water. Such water would be useless in improving physical performance, however, since the amount of oxygen in the blood who is exercising already more than the muscles can absorb.

Which of the following, if true, would serve the same function in the argument as the statement in boldface?

A) world-class athletes turn in record performances without such water
B) frequent physical exercise increases the body's ability to take in and use oxygen
C) the only way to get oxygen into the bloodstream so that it can be absorbed by the muscles is through the lungs
D) lack of oxygen is not the only factor limiting human physical performance
E) the water lost in exercising can be replaced with ordinary tap water

OA: C
I chose A. I ruled out D, E as they are irrelevant. I had trouble choosing between A, B, C.

B for me

The function of the bold statement is to undermine the effect of SuperOxy, so we need an option that would render superOxy useless.

A. the water lost in exercising can be replaced with ordinary tap water --> Water lost in exercise can be replaced by tap water, but superoxy contains more oxygen which could enhance performance. So A is out!
B. the amount of oxygen in the blood of people who are exercising is already
more than the muscle can absorb --> Correct. If the body is not able to absorb any more oxygen, then superoxy does not serve any purpose.
C. world-class athletes turn in record performance without such water --> True, but it doesn't say whether superoxy could enhance these performances.
D. frequent physical exercise increases the body’s ability to take in and use
oxygen -->Still no word about superoxy
E. lack of oxygen is not the only factor limiting human physical performance--> Still no word about superoxy

Do not agree with choice A here. I would go with B.

Conclusion:
Such water would be useless in improving physical performance, however, since the only way to get oxygen into the bloodstream so that it can be absorbed bye the muscles is through the lungs.

We need to provide an alternate reasoning to prove that such water is useless in improving physical performance, which is related to the amount of oxygen absorbed by the muscles from the bloodstream.

A. the water lost in exercising can be replaced with ordinary tap waterThis choice tells that the water lost during exercising can be replaced with ordinary water but does not give any information about improvement in physical performance after replacement.
B. the amount of oxygen in the blood of people who are exercising is already
more than the muscle can absorbThis choice exactly points that the amount of oxygen present in the people who exercise is already more and hence undermines the idea to use "SuperOXY" water to improve physical performance.
