Question

Quizplus · Accepted Answer

The drift speed of electrons is very slow, usually only on the order of centimeters per second or less. Thus, the correct option is D which says it's less than 1 cm/s. The other options are incorrect because they are either too fast (B) or unrelated to the question (A, C, E).
