Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. not suffer from.
The verb "does" is an auxiliary verb, and when used in negative sentences, it should be followed by the base form of the main verb.
Suffer is the base form of the verb.
Hence, the correct construction is "does not suffer", not "does not suffering."
