Thank you...

You are right in that the sentence 1 does not make sense and the sentence 2 does. Therefore omission IS ACCEPTABLE because the meaning is not ambiguous in this case. If both made sense, then the meaning would be ambiguous, and then omission would NOT BE ACCEPTABLE.

This question is a blatant copy of the official question, which can be found here: https://gmatclub.com/forum/antarctica-receives-more-solar-radiation-than-does-any-other-place-on-201871.html

Option C is incorrect because it is not parallel. On one hand, we have a full S/V clause = "the agriculture is so fertile"; however, on an another hand, we have clause with no verb = "the water reservoirs so efficient". Hence, why option C is incorrect and B is correct. For more information, please feel free to check the link that I posted above.

OFFICIAL EXPLANATION:

This question talks about Cherapunji, an actual region in India, that gets a lot of rainfall. The middle portion of the sentence is underlined, but it is important to pay close attention to the few words leading up to the underlnied portion of the sentence.

Notice the keyword "and" and the use of "so" before that keyword. This is a big clue as to what's going on in the sentence.

Meaning-wise, the sentence is saying this region has a lot of rainfall so the area gets pretty wet. It suggests that the area would normally get flooded because of so much rain. But by using the words "yet" - the author tells you that although you might think the place floods a lot - it actually doesn't because of two reasons.

One is that the agriculture is very fertile. So listing this one as a reason implies that the fertility of agriculture has something to do with its ability to reduce the amount of water in the area.

The second reason is the efficiency of the water reservoirs in reducing the presence of water. Without these two reasons, the author suggests what could or might happen by using the word "otherwise." Whether "otherwise" is the right way to phrase it is up to you to decide based on the available choices.

(A) are efficient, so that the water does not overflow on the land; otherwise,
so placement after effecienct isn't appropriate

(B) are so efficient that the water does not overflow the land; were it to do so,
exact le us hang on to it

(C) so efficient that the water does not overflow on the land, or else
so placement isn't appropriate

(D ) efficient, so that the water does not overflow on the land, or
same problem as a and the comma brings ina distorted meaning

(D) efficient so that the water does not only overflow the land; if it did
it means as though there is another possiblity '
Hence IMO B
