Explanation: An 8-bit storage register is designed to hold 8 individual binary digits, or "bits." Each bit represents a state of either a 0 or a 1. A flip-flop, such as an R-S flip-flop, is a fundamental digital circuit that can store exactly one bit of information. To construct a register capable of storing 8 bits, you need one flip-flop for each bit. Therefore, 8 separate flip-flops are required, with each flip-flop handling the storage of one specific bit within the 8-bit word. Options A, B, and D are incorrect because they do not provide the necessary one-to-one correspondence between the number of bits to be stored and the number of single-bit storage elements. This concept is foundational in digital electronics, which is critical for understanding the operation of modern amateur radio transceivers and digital communication systems.
