Explanation: In the sentence "Didn't Mr. and Mrs. Malhotra go for their son's wedding to Chennai?", the prepositions "for" and "to" are used to express different relationships within the sentence.
"Prepositions" are words that typically express a relationship between a noun or pronoun and other parts of the sentence. They can indicate direction, location, time, purpose, and other relationships. In this sentence, "for" and "to" are the prepositions that fulfill these roles.
The preposition "for" in the sentence "Didn't Mr. and Mrs. Malhotra go for their son's wedding to Chennai?" indicates the purpose of the trip. The purpose is to attend their son's wedding. This usage of "for" is common when expressing the reason or purpose of an action.
The preposition "to" in the sentence indicates the destination of the trip. The destination is Chennai. This usage of "to" is common when expressing movement towards a place.
It is important to note that "Mr. and Mrs." is not a preposition. It is a title used to address a married couple. It does not express a relationship between a noun and other parts of the sentence in the same way that prepositions do.
In summary, the correct answer is "Only (A) & (B)" because "for" and "to" are the prepositions in the sentence, each serving a specific function. "For" indicates the purpose of the trip, and "to" indicates the destination. Understanding the roles of prepositions in a sentence is crucial for proper sentence construction and comprehension.
