I'd choose B.

The subject of the independent clause (beginning after "macaques,") has to be the person who logged thousands of hours. That was Dr. Swenson, not chimps and other primates. Therefore, you can eliminate A, D, and E.

C is awkward. "Now" is misplaced.

Therefore, you are left with B, which is written correctly.

The subject of the independent clause (beginning after "macaques,") has to be the person who logged thousands of hours. That was Dr. Swenson, not chimps and other primates. Therefore, you can eliminate A, D, and E.

So we are left with B and C

The sentence has to be in present perfect because an event which starts in the past continues in the present too

Past event: Having logged thousands of hours watching primates

Current Event:

B. Dr. Swenson has come to believe that far from being natural-born killers, chimps and other primates

So this is the correct answer

Also check c

C. Dr. Swenson has now the belief that far from being natural-born killers, chimps and other primates

The bold face cannot be said to be a continuation of an event which started in the past.

Hope it Helps.

"B". the structure of 'B' seems better than that of 'C'.'
