Terminology — multiplexer select inputs: In data selectors, the select inputs are often referred to as address lines because they choose which input line is routed to the output. Evaluate the statement.

Introduction / Context:
Multiplexers (MUXes) map a binary code on select inputs to the choice of one input among many. Because those select bits effectively “address” one of the inputs, the term address lines is commonly used, especially when MUXes connect to memory or register banks.

Given Data / Assumptions:

• A 2^n-to-1 MUX uses n select inputs.
• Only one input is connected to the output for any select code.
• The naming reflects function, not necessarily memory addressing.

Concept / Approach:
Addressing means picking one resource from many using a binary code. In a MUX, the select pins perform exactly this role for input lines. Thus, calling them address lines is reasonable and widely seen in schematics and datasheets, although “select” remains the formal pin name.

Step-by-Step Solution:
Map select code to input index (e.g., S=101 selects D5).Recognize the selection is analogous to addressing.Conclude the terminology is acceptable and accurate.Therefore the statement is correct.

Verification / Alternative check:
Parts such as 74xx151 (8-to-1 MUX) label pins S2..S0; application notes often describe them as address inputs when used in memory/register selection roles.

Why Other Options Are Wrong:
Limiting correctness to 2:1 devices or memory maps confuses a general naming convention with a specific context.

Common Pitfalls:
Assuming address lines always refer to external memory buses; the concept applies anywhere one-of-N selection is required.

Final Answer:
Correct
