Explanation: In English grammar, pronouns are used to replace nouns in sentences to avoid repetition and to maintain clarity. The correct use of pronouns depends on the grammatical role they play in the sentence, such as subject, object, or possessive.
In the given sentence, "My grandparents live in Mumbai..... visit us often," the pronoun is needed to replace the subject "My grandparents." The subject "My grandparents" is a plural noun, referring to more than one person. Therefore, the pronoun used must also be plural.
The correct pronoun to use in this context is "they." "They" is a plural subject pronoun that correctly refers back to the plural subject "My grandparents." It maintains the grammatical structure of the sentence and ensures that the subject and verb agree in number.
Let's analyze the other options:
- "Them" is an object pronoun and cannot be used as the subject of a sentence. It would be incorrect to use "them" in this context.
- "Their" is a possessive pronoun and is used to show ownership. It is not appropriate to use "their" as a subject pronoun in this sentence.
- "He" is a singular pronoun used to refer to a male subject. Since "My grandparents" is a plural subject and includes both male and female individuals, "he" is not the appropriate pronoun to use.
Understanding the correct use of pronouns is essential for maintaining grammatical accuracy and clarity in writing and speaking. In this case, "they" is the correct choice because it correctly refers to the plural subject "My grandparents" and maintains the grammatical structure of the sentence.
