Final answer:
The subject is 'man' and the correct answer is 'Lives'.
Step-by-step explanation:
The correct answer is a. Lives.
In this sentence, 'the man' is the subject. Since 'man' is a singular noun, the verb that follows should be in the singular form as well. 'Lives' is the correct form of the verb 'to live' for third person singular subjects like 'the man'.
For example, if we replace 'the man' with a singular noun like 'John', we would say 'John lives on my street.' However, if the subject was plural, we would use the verb 'live', as in 'The men with all the cats live on my street.'
