The answers is between A and D.
For answering you should be knowing the difference between sufficiency and necessary Also necessary and sufficient indicators.

Now the stimulus says:
reptiles are incapable of making alterations in behavior---------->>>>incapable of complex reasoning .
We can say it as
capable of complex reasoning ---------------->>>> capable of making alterations in behavior.


Thank you guys for the explaination. In the first attempt I voted for A . But this question is from casuality :

Stimulus suggest that "complex reasoning cause major changes in the behaviour" -- Option E

Where as in "A" it is opposite.

Now A says:
Major changes in behavior -------->>>>>>capable of complex reasoning (this makes our necessary statement as sufficient and our sufficient statement as necessary, note Only if refers a necessary condition)


refer to D
capable of complex reasoning ---------->>>>>>able to make changes (This matches our conclusion. Hence correct .)
