Correct answer

Because the braking on the wheels of the same axle is not exactly equally effective.

It may be due to unequal braking effectiveness at the wheels of the same axle. Pulling while braking can have several causes, including uneven wear or a brake fault, and needs professional inspection. It does not by itself establish that wheel alignment is the required repair. Engine oil and supposed injection-system pressure into power steering do not explain the proposed cause in the other options.
