Which bus carries command signals such as read and write?

Correct answer: Control Bus

The control bus carries command and timing signals that coordinate operations among the processor, memory, and peripheral controllers. Signals such as read, write, interrupt, and clock-related coordination tell components what action to perform and when. The data bus carries values, and the address bus identifies locations; neither one primarily carries commands. A video bus is not the general control pathway. Therefore, option C is correct.
