Explanation:
The correct negative form of the sentence "She ___ like spicy food" is option 'b) doesn't.' Let's understand why this is the correct choice.

Subject-Verb Agreement:
When using the third person singular pronouns (he, she, it), we need to use the auxiliary verb 'does' to create the negative form of a sentence. The base form of the verb is used after 'does not' or 'doesn't.'

Subject: She
In this sentence, the subject is 'she,' which is a third person singular pronoun. Therefore, we need to use 'does' to create the negative form.

Verb: like
The verb in the sentence is 'like.' The base form of the verb 'like' is used after 'doesn't' to create the negative form.

Negative Form:
Combining the subject 'she' with the auxiliary verb 'does' and the base form of the verb 'like,' we get the negative form: 'She doesn't like spicy food.'

Incorrect Options:
- Option 'a) don't' is incorrect because 'don't' is the negative form used with the first and second person pronouns (I, you, we, they), not the third person singular pronoun 'she.'
- Option 'c) isn't' is incorrect because 'isn't' is the contraction for 'is not,' which is used with the verb 'to be,' not with the verb 'like.'
- Option 'd) aren't' is incorrect because 'aren't' is the contraction for 'are not,' which is used with the verb 'to be,' not with the verb 'like.'

Therefore, the correct negative form for the sentence "She ___ like spicy food" is option 'b) doesn't.'
