IMO C

Argument says dart causes infertility

If we reject any other reason that could have caused infertility, then that should be a correct answer choice.

C says stress is not an alternate cause of infertility . (Its a defender Assumption).

Conclusion: Frequent tranqualizing causes less reproduction.
Proof: Female rhino frequently recollered has less babies than non-collered or non tranquilled.

Now take C and negate it.

Any stress on female rhino due to tranqualizer has negitive effect on fertility [ removed no]

This strenghtens the conclusion or both are equal. [strengthner] Wrong

A) does not speak about fertility
D) male rhino cannot reproduce
E) other mammels is out of scope.

Now let us take B and negate it.
Fertility rate of un-collered rhino's are not increasing => Tranquils have no effect on fertility.. this weakens the concusion that tranquls cause less fertility.

First take: 640 (50M, 27V) - RC needs 300% improvement

IMO C

I was down with B and C. I rejected B because I am not bothered about increasing fertility rate.
As correctly pointed out earlier,C is a defender assumption.

"Target Test Prep is the closest to the official version of the GMAT exam, about 99% accuracy in terms of the quality and quantity of information. The course has excellently created singular sets of focused lessons and tests for every possible topic that one could come across in the official GMAT exam."

"The TTP course maximizes the efficiency of the time you spend studying. It will take time and effort but I could almost guarantee that if you complete the course exactly as it is laid out you will get an amazing score. They also have a very responsive team willing to help with any questions you might have."

"TTP has two things that I think no other test prep company offers: A teaching approach that reinforces understanding and an attitude that will give you the mental preparedness needed to succeed on the test. TTP gives you a deep understanding of the concept you need to know while teaching you how to think."
