Topic: Subject Verb Agreement,

Best Answer Explained in Below-:

The phrase 'No man can --- alone.' requires a verb that fits grammatically in the context of expressing ability or possibility. In English, "can" is a modal verb that is used to indicate ability, possibility, or permission. Modal verbs are typically followed by the base form of the verb, which is known as the infinitive without "to."

Looking at the options provided:

- A) "lives" is in the third person singular present tense, which is not suitable following "can."
- B) "live" is the base form of the verb, making it the correct choice to follow "can."
- C) "living" is a gerund (verb form used as a noun) and doesn't fit the structure needed here.
- D) "lived" is the past tense form, which is also incorrect in the context.

Therefore, only option B, "live," correctly completes the sentence as 'No man can live alone.', aligning with the grammatical rules of English and conveying the intended meaning that no person is capable of existing in isolation.
