The bold face line supports the conclusion and C does the same thing.
there is no point in drinking the water since oxygen will come only from lungs

I agree with icha. Let's break down the process of doing this question
Boldface questions are awesome because you immediately know the type of task you're going to be undertaking. The question pops up on your screen, you see bold words and you know "I'm going to have to figure out something related to the function of the bold words!" The slightly trickier twist in this question is that you not only have to identify the function of the boldface portion, but you must find the choice that serves the same function. Extra work for us--boo.
But as is true for many CR questions, the first task is to identify the conclusion. What is the conclusion here?
-FACTS (premises)
(1) amt of oxygen absorbed by muscles from blood limits physical performance
(2) entrepreneurs have begun selling SuperOxy (water w/extra disolved oxygen) at gyms etc
(3) BOLD STATEMENT: amount of oxygen in the blood of someone who is exercising is already more than what muscle cells can absorb
-CONCLUSION/BIGGEST (and here the *only*) CLAIM
*Such water would be useless in improving physical performance
-The conclusion and the boldface are linked by the word "since"-- this tells you that the boldface statement is being used to support the conclusion:
-Since X, Y (X, therefore Y)
For example...Since I like you, I will buy you a present. (I like you, therefore I will buy you a present)
So which choice also supports the conclusion? You can now think of this as a STRENGTHEN question.
(A) is out of scope. Who cares what athletes can do without the water? We want something that will help us prove the conclusion that the water is useless in improving physical performance. Eliminate.
(B) is either out or scope or, at best, would weaken the conclusion. Do people at gyms necessarily work out "frequently?" There's no way to know. Even if they do, and the body is therefore able to take in and use more oxygen, that would mean the water might be able to be absorbed and therefore get rid of one of the limiting factors of physical performance-- this would weaken the conclusion. Eliminate.
(C) is a possibility-- if the ONLY way (pay attention to those red-flag words!) to get oxygen into the blood (and from there into the muscles) is through the lungs, then drinking the water would certainly not help improve physical performance, since the extra oxygen in water couldn't be absorbed by the body anyway! This is likely our answer,but keep going to be safe.
(D) is out of scope. The fact that lack of oxygen is "not the only factor" does not tell us anything about this argument, which deals with the limiting factor of oxygen (and the possibility of overcoming it with magic water). Eliminate.
(E) is out of scope. We don't care about the water lost in exercising. We care whether SuperOxy water can help us improve physical performance by helping us get more oxygen into our bloodstream. Eliminate.
(C) is our answer.
