• SPLIT #1: pronoun/noun disagreement

The pronoun their is plural and does not agree with the logical antecedent an animal, which is singular.

Eliminate options A and D

• SPLIT #2 - seeming vs. seemingly

Seeming is the adjective form and must modify a noun.
Seeming means ostensible or not true to appearances: I was not persuaded by his seeming concern about wearing masks.

Seemingly modifies the adjective limitless; we need the adverb, seemingly.
Options B and D both use seeming. (D is already gone.)

Eliminate B

• idiom: in this context, a range of is idiomatic.
→ True, it is idiomatically correct to say that something ranges from A to B, but that idiomatic expression is not in play.
This sentence talks about a range of X and Y.

Option C incorrectly uses range from rather than range of.

Eliminate C

The answer is E
