Select the option to replace the incorrect word in the following sentence.
Chotu is a bright young child, who yearn to go to school but works in his uncle’s dhaba.

The correct option to replace the incorrect word in the sentence is yearns.

Explanation:
1. Identify the subject: In the given sentence, the relative pronoun "who" refers back to the subject "Chotu" (or "a bright young child"), which is a third-person singular noun.
2. Subject-Verb Agreement: A singular subject requires a singular verb in the present simple tense. The base verb "yearn" is plural, whereas "yearns" is the third-person singular form.
3. Tense Consistency: The rest of the sentence uses the simple present tense ("is", "works"). Therefore, the verb inside the relative clause must also be in the present simple tense to maintain parallel tense consistency.

Thus, replacing yearn with yearns makes the sentence grammatically correct:
"Chotu is a bright young child, who yearns to go to school but works in his uncle’s dhaba."
