Question

Fill in the blank with the most appropriate word.
They were all strangers to me. I'd met _________ of them before.

• A. either
• B. neither
• C. none
• D. all

Answer 1

The correct option is C none

A word that can function as a noun phrase used by itself and that refers either to the participants in the discourse or to someone or something mentioned elsewhere in the discourse is a pronoun.

Either and neither can be used in several ways: adverbs, determiners, pronouns and conjunctions. While 'either' has a positive connotation, 'neither' holds a negative significance. You will always find them paired up this way: either/or and neither/nor. But in this case, none of the them are paired. It is the wrong option.

None has a plural sense (“not any”) as well as a singular sense (“not a single one”). It is the correct option.

"All" is the wrong option here

Option C is correct.
