This is a missing premise question, but the wording is a little confusing so let's map out the prompt so we can discover the gap.
P: genuine creative genius -> dissatisfied with habitual assent P: dissatisfied with habitual dissent -> seek out controversy P: seek out controversy - > demonstrate falsehood of popular beliefs
C: thus, these rare innovators (meaning genuine creative geniuses) tend to anger the majority
In order to get to the conclusion, we need something to connect genuine creative geniuses to angering the majority. The existing premises only get us to "genuine creative genius - > demonstrate falsehood of popular beliefs." We need a premise to get us to the conclusion, which is "demonstrate falsehood of popular beliefs - > anger the majority."
To answer your question about option E, let's map out what logical conclusions we could draw from the premise proved by E.
E says "anger the majority -> dissatisfied with habitual assent."
Continuing down the logical chain "dissatisfied with habitual assent -> seek out controversy," then "seek out controversy -> demonstrate falsehood of popular beliefs."
The logical chain ends there, so angering the public is not logically tied at all the being a genuine creative genius
