I am going with C!

(A) not unlike that of Rosa Parks, who refused

(C) like (Rosa Parks and her refusal

Clearly the answer is B. Except B all the other choices have comparison problems.

A) Awkward construction (no verb) + wrong comparison.
C) 'that of' in C is redundant
D) wrong comparison. "Volatility for a balanced portfolio" is being compared to overall stock market instead of "volatility of overall stock market".
E) Little different sentence structure but same error as that in D. "Volatility of a balanced portfolio" is being compared to overall stock market instead of "volatility of overall stock market".

Hope that helps.

Your explanation is correct but you selected wrong answer.
Actually, here main thing is that one should understand the use and meaning of AS ... AS construction.

I understood it now. THAT OF is not requited.

So B is perfect here.

Ah! Finally an easy one! It is the as X as Y construction in play here and B is clearly the answer. IN C that of is referring to nothing.

That refers to courage in the OG question whereas that has no referent in question posted by the OP. as X is as volatile as Y IDIOM
