Identifying the Part of Speech:

In the sentence "The red ball bounced high," the underlined word is "red." To identify its part of speech, we need to consider its function in the sentence.

- "The" is a definite article that introduces a noun.
- "Ball" is a noun that refers to a round object used in games and sports.
- "Bounced" is a past tense verb that describes the action of the ball.
- "High" is an adverb that modifies the verb "bounced," indicating the degree or extent of the action.

Therefore, the only option left is "C) Adjective," which correctly identifies "red" as an adjective that describes the ball.

Explanation:

An adjective is a word that describes or modifies a noun or pronoun. It provides more information about the noun, such as its color, size, shape, or other qualities. In the sentence "The red ball bounced high," "red" is an adjective that describes the color of the ball. Without the adjective, the sentence would be incomplete and less descriptive.

In general, adjectives can be placed before or after the noun they modify, depending on the context and style of the sentence. For example, we can also say "The ball was red" or "The bouncing ball was red." In either case, "red" functions as an adjective that adds meaning and detail to the noun.

In conclusion, identifying the part of speech of a word requires analyzing its role in the sentence and understanding its grammatical function. In this case, "red" is an adjective that modifies the noun "ball" and provides additional information about its appearance.
