A multiplexer with a 4 - bitdata select input is aa)4 : 1 multiplexerb...
Explanation:

A multiplexer is a combinational circuit that selects one of the input lines and forwards the selected input to the output. The selection of the input line is controlled by the select inputs.

The select input of the multiplexer specifies which input line is to be selected and forwarded to the output. The number of input lines in a multiplexer is equal to 2^n, where n is the number of select inputs.

In this question, the multiplexer has a 4-bit data select input. This means that the multiplexer has 2^4 = 16 input lines. Therefore, the correct answer is option C, which states that the multiplexer is a 16:1 multiplexer.

To summarize:

- A multiplexer is a combinational circuit that selects one of the input lines and forwards the selected input to the output.
- The selection of the input line is controlled by the select inputs.
- The number of input lines in a multiplexer is equal to 2^n, where n is the number of select inputs.
- In this question, the multiplexer has a 4-bit data select input, which means that it has 2^4 = 16 input lines.
- Therefore, the correct answer is option C, which states that the multiplexer is a 16:1 multiplexer.
