Explanations:Adverbs are words that modify verbs, adjectives, or other adverbs, providing additional information about the manner, time, place, or degree of the action or state described. In the context of the sentence "Nikhil _____ invited his cousin Dilip to visit him in Chennai," the adverb should reflect the manner in which Nikhil invited his cousin. The relationship between Nikhil and Dilip is that of cousins, which typically involves a close and affectionate bond.
The correct adverb in this context is "warmly." This adverb indicates that Nikhil invited his cousin in a friendly and welcoming manner, which is appropriate for the relationship between cousins. The word "warmly" conveys a sense of affection and hospitality, making it the most suitable choice for the sentence.
Option A, "safely," is incorrect because it does not fit the emotional context of the sentence. While safety is important, it is not the primary concern when inviting a cousin to visit. The focus should be on the emotional tone of the invitation, which is best conveyed by "warmly."
Option C, "Either (A) or (B)," is incorrect because "safely" does not fit the context, and thus the combination of the two options cannot be correct. The sentence requires an adverb that conveys a welcoming and affectionate manner, which is best represented by "warmly."
Option D, "Neither (A) nor (B)," is incorrect because "warmly" is the appropriate adverb to use in this context. The sentence requires an adverb that reflects the emotional tone of the invitation, and "warmly" is the correct choice.
Understanding the context and the relationship between the characters is crucial in selecting the appropriate adverb. In this case, the affectionate and welcoming nature of the invitation is best conveyed by "warmly."
