【正确答案】 B

【答案解析】Rhetorical construction; Agreement
The phrase beginning with having been modifies the noun phrase ordinary men and women. In cases like this, it is best to use a full relative clause, starting with that or a relative pronoun such as which or who, instead of a clause with the -ing form of the verb. Also, themselves is the correct form of a reflexive pronoun to refer back to the plural noun phrase ordinary men and women.
A A phrase starting with the -ing verb form, instead of with that or who, is awkward in this context.
B Correct. A relative clause correctly beginning with who is used, and themselves is the correct form for the reflexive pronoun.
C Himself or herself is not the correct form for the plural reflexive pronoun.
D Though the relative and reflexive pronouns are grammatically correct, the relative clause (the clause that starts with of whom) is unnecessarily long and complex.
E Himself or herself is not the correct form for the plural reflexive pronoun.
The correct answer is B.
