Correct Answer:
B. bright
Foundational Concept: An adjective is a word that describes or modifies a noun or pronoun, providing more information about its qualities, characteristics, or quantity.
Correct Option: The word "bright" describes the noun "sun," indicating its quality or appearance. Therefore, "bright" functions as an adjective in this sentence.
- Sun: "Sun" is a noun, the subject of the sentence, referring to the celestial body.
- Warmed: "Warmed" is a verb, representing the action performed by the sun.
- None of these: This is incorrect because "bright" is clearly an adjective.
