(C) for me. Time taken 01:38.

Splits used:

1. has reversed/reversed/had reversed
2. is meeting/will meet

(A) "reversed" is simple past tense. This sentence implies that the impact of Project Tiger is no more relevant. It happened in past and its effects does not exist in present. Meaning, it could be that the Project Tiger reversed the decline in population in past and now again the decline is in motion. This does not seem to be the intended meaning. So, it is a good reason to ditch "simple past tense" in this case and "simple present perfect" would be a much better choice here. Also, "within" when presenting a period of time often takes the tense- present perfect.

(B) Though this choice takes the correct verb tense "present perfect", it uses the incorrect "present continuous" in the later part of the sentence. Present continuous tense is used to depict an action that is in motion right now/as of the moment. The meeting is not happening right now, it "will" happen tomorrow, so the correct tense should be "simple future" tense. Eliminate this choice too.

(C) This choice uses correct tenses. And although some may point fingers towards the "for the discussion of" structure, I see no reason why it could be considered wrong. Yes, "to discuss on" is much better than "for the discussion of". But the other choices have clear identifiable errors and this choice is sans any. Lets wait for the OA.

(D) This choice is incorrect for using "reversed". See (A) above for more on this.

(E) "had reversed" is unnecessary here. Past perfect is used to depict two related past events. What's the second past event here? None. Reject.
