Step 1: Identify the subject of the sentence.
The subject of the sentence is "Ansha".
Step 2: Determine the number and person of the subject.
"Ansha" is a singular noun, referring to a third person (he/she/it).
Step 3: Apply the rules of subject-verb agreement for the simple present tense.
In the simple present tense, for a third-person singular subject (he, she, it), the verb typically takes an "-s" or "-es" ending.
Step 4: Evaluate the given verb options.
(1) want: This form is used with plural subjects (we, you, they) or the first-person singular (I).
(2) wants: This form is correctly used with a third-person singular subject like "Ansha" in the simple present tense.
(3) wanting: This is a present participle and would typically be used with a form of "to be" (e.g., "Ansha is wanting"), or as an adjective/noun. It is not a standalone verb in this context.
(4) become: While "become" is a verb, it doesn't fit the context of wanting to be something. "Ansha wants to become a space scientist" would be grammatically correct if "wants" were followed by "to become," but "become" alone doesn't convey the same meaning as "wants to be." The sentence structure "Ansha [...] to be" specifically calls for a verb that completes the desire or intention.
Step 5: Conclude the correct verb form.
"Wants" is the correct form of the verb for the singular third-person subject "Ansha" in the simple present tense.
(2) wants
