(A) Martin Luther is the best known of them
(B) the best known is Martin Luther
(C) the better known of them was Martin Luther
(D) Martin Luther is better known
(E) the best known one was Martin Luther

OA is B. please explain

We already start with Of the people who brought about the Reformation, so using "of" a second time is unnecessary.
(A) Martin Luther is the best known of them
(C) the better known of them was Martin Luther
ELIMINATE A and C

(D) Martin Luther is better known
We use "better" when comparing TWO things/people. Use "best" for more than two.
Since it's likely that more than two people brought about the Reformation, ELIMINATE D

(E) the best known one was Martin Luther
We don't need one here. It's redundant.
Stating that the best known person is Martin Luther implies one person. So, we need not state that Martin Luther is one person. ELIMINATE E

Answer: B
