The function of a multiplexer (also known as a mux) is to assert the selection output for the memory location corresponding to the input address bit stream. In simpler terms, a multiplexer is a device that selects between several input signals and forwards the selected input into a single line. It's like a multiple-input, single-output switch.

Here's a step-by-step explanation:

1. The multiplexer receives multiple input signals.
2. It also receives a selection signal that determines which input to forward.
3. Based on the selection signal, the multiplexer forwards the corresponding input signal to its single output line.

So, the correct answer from your options is: "Asserts the selection output for the memory location corresponding to the input address bit stream."
