Solution (By Examveda Team)

In the sentence, "When did Fatih Sultan conquer Istanbul? Istanbul was conquered by Fatih Sultan in 1453," the past tense passive voice is used to describe an action that was performed on the subject (Istanbul). This construction indicates that Istanbul was the object of the action of being conquered.

The correct form for the sentence is "Istanbul was conquered by Fatih Sultan in 1453."

The other options are not suitable because they do not accurately convey the intended meaning:

Option B: conquered
This option uses the simple past tense and does not use the passive voice. It does not indicate that Istanbul was the object of the action of being conquered.

Option C: be conquered
This option is in the infinitive form and does not create a grammatically correct sentence in this context.

Option D: is conquered
This option uses the present tense and is not appropriate for describing an action that occurred in the past.

Therefore, the correct answer is Option A: was conquered.
