A:
My aunt who lives in Mumbai is a doctor.
B:
My aunt, who lives in Mumbai, is a doctor.
C:
My aunt, who lives in Mumbai is a doctor.
D:
My aunt who lives in Mumbai, is a doctor.
Explanation
The correctly punctuated sentence is:
B) My aunt, who lives in Mumbai, is a doctor.
Explanation: This sentence uses commas to set off the relative clause "who lives in Mumbai" because it provides additional information about the subject "my aunt." The commas indicate that the relative clause is nonessential to the main sentence, meaning the sentence would still make sense without that information. Therefore, option B is the correct choice as it uses the appropriate punctuation to indicate the nonessential relative clause. Options A, C, and D either lack necessary commas or place them in incorrect positions, resulting in incorrect punctuation.
