GMAT Sentence Correction (SC) | Re: The javelin has a sharp point, which is more obviously

Answer to this question is B. Choice is between B and E.

B - "obviously more dangerous" usage is correct
E - "more obviously dangerous" is incorrect usage of More.

1. More modifies whatever comes immediately after it. Here More has to modify dangerous.
2. More is an adjective, cannot modify an adverb.

Seeking clarification on Why the correct answer here is E !! It is incorrect and is confusing my understanding.
