I (see) a great film yesterday.

Correct option is A

• A) Saw: This past tense form is correct because "yesterday" indicates a past time frame.

• B) Seen: This form is incorrect because "seen" is the past participle and needs a helping verb (e.g., "have seen") to be correct.

• C) Sees: This form is incorrect because it is the third person singular present tense, which doesn't fit the past tense context.

• D) See: This base form is incorrect because it doesn't fit the past tense context.
