d“he knew the different parts of speech, he could paraphrase, analyze and construct sentences.”

The following line from "Educate Yourself" by Marcus Garvey is a fact:

D. “He knew the different parts of speech, he could paraphrase, analyze and construct sentences.”

This line is a fact because it is stating what "he" knew and what "he" could do.  It is not expressing an opinion about "his" abilities. It is rather expressing an objective truth that is not up for discussion.

Why not A, B or C?

These statements show opinions, not facts. Each person can have different perspectives about the same subjects. In A, B and C, Garvey is expressing his perspective on those subjects. The statements in A, B and C show a subjective perspective and therefore are up for discussion, while D shows an objective truth.
