Answer:
To answer the question "What is she eating right now?" correctly, we need to understand the grammar rules related to present continuous tense and the context of the sentence.

Present Continuous Tense:
The present continuous tense is used to describe actions that are happening at the moment of speaking or around the present time. It is formed by using the present tense of the verb "to be" (is, am, are) followed by the present participle (-ing form) of the main verb.

Context of the Sentence:
The question asks about the action of eating that is currently happening. Therefore, we need to use the present continuous tense to describe the action in progress.

Explanation:
The correct answer to the question "What is she eating right now?" is "Is she eating." Here's why:

1. Subject:
The subject of the sentence is "she," referring to a female person.

2. Present Continuous Tense:
To form the present continuous tense, we use the present tense of the verb "to be" (is) plus the present participle (-ing form) of the main verb.

3. Verb:
The main verb in the sentence is "eat." To form the present participle, we add "-ing" to the base form of the verb, resulting in "eating."

4. Formation of the Sentence:
By combining the subject, the present tense of the verb "to be" (is), and the present participle of the main verb ("eating"), we get the correct sentence: "Is she eating."

5. Meaning:
The sentence is asking about the current action of eating that the female person is engaged in. It implies that the action is happening right now or around the present time.

Summary:
The correct answer to the question "What is she eating right now?" is "Is she eating." It follows the grammar rules of the present continuous tense and accurately describes the ongoing action of eating that the female person is currently involved in.
