✔ 最佳答案
A split-ring commutator converts AC to DC so the answer is d.As regards answers from other answerers, all generators have brushes and the commutator on its own converts to DC This does not have a fixed value which is what I assume "approximate DC" is supposed to mean in one of the answers you received.

commutator - actually inverts the direction to approximate DC

Commutator (+ brushes).
The commutator has separated segments to contact the brushes.
