The melting of world glaciers, measured consistently from the early 1990s until the present, seems like it is corroborative that average global temperatures are inexorably rising.

A. like it is corroborative that -> "Like" is redundant to use. Incorrect.
B. as if to corroborate -> We already have "seems", there is no need to say "Seems as if". Incorrect.
C. to corroborate that -> "that" connects two ICs perfectly. Let's keep it.
D. corroborative of -> seems is followed by "to +verb". Incorrect.
E. like a corroboration of -> Same error as A. Incorrect.

So, I think C.

Official Explanation

Split #1:  noun/verb/adjective split. Here we get the same root word appearing in its adjective form (corroborative), its verb form (corroborate), and its noun form (corroboration). This is an action word. As a general rule, the GMAT prefers when action words are verb. Furthermore, it is almost invariably the case that putting the word in verb form will make the entire sentence more concise, more direct, and more elegant than if the word had been in noun or adjective form. We have a strong preference for (B) & (C) on these grounds.

Split #2:  what follows the word "seems"? If we are comparing two object, two nouns, P and Q, we could say "P seems like Q." The "seems like" construction would be fine for a simple noun. If we are describing P as some adjective, we could say "P seems  ;" this would work for a simple adjective. Here, though we have an action happening after the "seems": for this case, the verb "seems" idiomatically takes the infinitive: "seems to do X." Again, (B) and (C) are the only ones with verb. Furthermore, (B) is strangely hypothetical in way that is not consistent with the situation. At this point, we strongly suspect (C) is correct.

Split #3:  the clause "average global temperatures are inexorably rising" is a full clause with a bonafide  + . It must begin with the word "that." In colloquial speech we can drop the word "that" ("Her note seems to indicate she is angry") but on the GMAT, with its higher level of formalism, we always need the "that" before a clause ("Her note seems to indicate that she is angry"). Only choices (A) & (C) have the required word "that."

On the basis of these splits, it's clear that (C) is the best possible answer.

Can someone explain why (d) is wrong?

Doesn't (d) follow the structure of:  Gerund + seems + adjective

Isn't option (d) similar to this sentence: "Swimming seems easy until you actually do it"

Hello  yogendraaaa ,

We hope this finds you well.

To answer your query, since the information that "The melting of world glaciers" corroborates is expressed in an independent clause - "average global temperatures are inexorably rising" - "that" must be used here; if the sentence had used the present participle ("verb+ing" - "rising" in this case) as a noun modifier rather than the active verb "are rising", then "corroborative of" would have been correct.

We hope this helps.
All the best!
