all choices except d are wrong.

1. compared to alligators, crocodiles are better able.... - wrong. two comparison tool can't be used at the same time

these are the two acceptable construction :

compared to alligators, crocodile are able to ....
crocodiles are better.....than alligators are/are alligators.

comparison such as "better/more" should be always followed by "than".
----

this alone eliminates A,C, and E.

B - improper comparison : unlike alligator's tongue, salt...

D is correct in all sense.

@Birottam

In option E, had it been "compared to" and not "compared with", would that have made it correct?

And, we use "compared with" to compare 2 essentially similar things and "compared to" to compare 2 dissimilar things. In this case, alligators and crocodiles belong to the same family (i think so), so shouldn't "compared with" be correct?

Actually there is no difference between "compared to" vs "compared with". Both are acceptable and interchangeable. Refer OG-11 SC#17 explanation.

The major problem in E - the use of two comparison structure.

compared with..., crocodiles are better... - as I explained in my above post. Moreover,"better" is used for comparison,an adverb of comparison, and always followed by "than".

compared to Jim, jack runs fast. - correct.
Jack runs faster than Jim. - correct.

Original construction : jack runs faster than jim runs. "faster than..." is an adverb of comparison.

compared to jim, jack runs faster. - incorrect.

for more on this usage, refer Og-12 SC#123. One can easily eliminate A,B and D based on this usage.
