Which of the following is an accurate statement?

A. AC Generators produce current that is pulsating, but always remains positive.

B. Step-down voltage transformers have a different number of turns in the primary than in the secondary winding, so they change the incoming voltage to a higher voltage.

C. DC Generators produce current with a voltage that changes from positive to negative.

D. Step-up voltage transformers have a lower number of turns in the primary than in the secondary winding.

The correct option is D.

A step up voltage transformer is a type of transformer which increases voltage from primary to secondary turns. The transformer has more secondary winding turns than primary winding turns. A step up transformer is designed to increase voltage because high voltage increases efficiency.
