Correct option is C
The correct substitution of the highlighted words is (c) try.
Explanation: The subject “you” is second person and always uses the base form of the verb without “-s” in the present simple tense.
Incorrect: “you tries”
Correct: “you try”
Grammatical rule used:
· Present simple tense: subject + base verb
· Only third-person singular (he, she, it) takes “-s” or “-es” with the verb.
· Example:
· • He tries to win.
· • You try to win.
Information Booster: Auxiliary verbs like “do/does” also follow the same subject-verb agreement in questions and negatives.
