Which is the correct way to complete the sentence: "I ______ Sidra yesterday."?

Explanation

The correct answer is 'saw' because it is the simple past tense used for actions completed at a specific time in the past. 'Have seen' is present perfect, which is not appropriate with a definite past time like 'yesterday.' 'Had seen' is past perfect, which requires another past event to relate to. 'Seen' alone is incorrect without an auxiliary verb.
