Topic: Degree of Comparison,

Best Answer Explained in Below-:

The term "wiser" in the statement "Children are wiser than their elders" is in the comparative degree because it compares the wisdom of two groups: children and their elders. The comparative degree is used to show differences between two entities, often formed by adding the suffix "-er" to adjectives or using "more" before them. In this case, "wise" is the base adjective, and by adding "-er," it transforms into "wiser" to indicate that children possess a greater degree of wisdom relative to their elders.

This contrasts with the positive degree, which simply expresses a quality without comparison (e.g., "wise"), and the superlative degree, which indicates the highest degree of a quality among three or more subjects (e.g., "wisest"). Since we are explicitly comparing the wisdom of children to that of elders, "wiser" clearly fits the criteria for the comparative degree. Thus, option C is correct because the statement implies that children exhibit more wisdom compared to their elders, establishing a comparison between the two groups.
