A. It had been expected by Alexander that he would conquer the world
B. It was expected by Alexander that he would conquer the world
C. It was expected by Alexander that he should conquer the world
D. It was expected by Alexander that he will conquer the world
Explanation
The correct answer is: It was expected by Alexander that he would conquer the world.
This sentence is in the passive voice, whereas the original sentence is in the active voice. The meaning of the sentence remains the same, but the focus shifts from Alexander (the doer) to the expectation (the action).
