IMO A.

The list is singular so exhibits is the correct verb(C, D and E ruled out). In B, "has been expanded and includes" seems wrong to me and it also changes the meaning.

Answer - D

But in this case we violate parallelism of "either" constraction:
either using the right or the left hand

My bad.. didn't read properly.

IMO D

Animals - Plural. so exhibit is the correct verb(A and B ruled out).

Between C, D and E - It comes down to idiom - Preference for is the correct idiom.

"preference for" is the right idiom. Pick D

IMO D

1. Animals that exhibit
2. either X or Y (X and Y should be parallel)
3. Preference for X and Y (Preference for X or Y), whereas prefer X to Y

Guys...

here subject is not the animals BUT LIST

Ans must be B

am not sure abt IDM but it can't take priority over Subject -Verb basic rule..

D is correct,

"exhibits" in A and B is wrong,should be "exhibit"
"either using the right or the left hand " in C is not parallel
"either using the right or the left hand " in E is not parallel

'the list' doesn't 'exhibit preference' but the animals 'exhibit preference' for using either hand so i think 'exhibit' is correct.
Also i think the correct idiom is 'preference for'.
IMO D is correct.

Let me finish:

1. List can not exhibit preference, so animals that exhibit preference is correct.
=> This rules out A and B.

2. "Either X or Y" is correct, where x and y must be parallel.
=> E and C are out.

=> either using x or using y. is correct idiom.

BUT "either using X or Y" is not correct.

Answer is D.
