Correct option is A

Option (a) contains an error.
Error Identification: The verb "has" is incorrect for the subject "Men", which is plural and requires "have."
Grammatical Explanation: "Men" is a plural noun, so the correct auxiliary verb is "have" instead of "has."
Corrected sentence: "Men who have risen by their own exertions are always respected."
Explanation: The verb must agree with the plural subject "Men," so "have" should replace "has."
