Explanations:Prepositions are an essential part of English grammar, used to show the relationship between a noun or pronoun and other parts of the sentence. In the context of the sentence "Didn't Mr. and Mrs. Malhotra go for their son's wedding to Chennai?", we need to identify the correct prepositions that fit the context.
The sentence contains two prepositions: "for" and "to". The preposition "for" is used to indicate the purpose of the trip. In this case, the purpose is to attend their son's wedding. The preposition "to" is used to indicate the destination of the trip, which is Chennai. Both prepositions are necessary to convey the complete meaning of the sentence.
It is important to understand the function of each preposition in the sentence. "For" is used to express the reason or purpose of an action, while "to" is used to indicate movement towards a place. In this sentence, both prepositions are used correctly to convey the full meaning of the sentence.
Option C, "Mr. and Mrs.," is not a preposition and does not fit the context of the question, which specifically asks for the correct preposition(s). Therefore, it is not the correct answer.
Option D, "Only (A) & (B)," is the correct answer because it correctly identifies both "for" and "to" as the appropriate prepositions in the sentence. Both prepositions are necessary to convey the complete meaning of the sentence, indicating both the purpose and the destination of the trip.
Understanding the correct use of prepositions is crucial for constructing grammatically correct sentences and conveying clear meaning. In this case, the sentence requires both "for" and "to" to accurately describe the purpose and destination of the trip.
