B)galvanic corrosion.

Question

Quizplus · Accepted Answer

Dissimilar metals create an electrochemical cell and galvanic corrosion occurs. To prevent this, a separator is used which creates an insulating barrier between the metals. Therefore, option B is correct. Option A is incorrect as atmospheric corrosion can still occur even with a separator in place.
