Explanation:

The correct answer is option 'A' - Round.

To understand why the correct answer is "Round," let's break down the sentence and analyze the different words and their roles:

1. The - This is an article that indicates that something is being referred to.

2. Round - This is an adjective that describes the noun "ball." It tells us the shape of the ball.

3. Ball - This is a noun that refers to the object in question, which is a round ball.

4. Bounced - This is a verb that describes the action of the ball. It tells us what the ball did.

In the given sentence, the word "round" is an adjective that describes the noun "ball." It tells us the shape of the ball, indicating that it is not flat or square, but circular in shape. Since the question asks for the word that correctly identifies the shape of the ball, the correct answer is "Round."

The other options, "Ball" and "Bounced," are also important words in the sentence, but they do not directly describe the shape of the ball. "Ball" is the noun that refers to the object, and "bounced" is the verb that describes the action of the ball. However, neither of these words provides information about the shape of the ball.

In conclusion, the correct answer to the question is "Round" because it is the adjective that accurately describes the shape of the ball in the given sentence.

The correct answer is (a)round
