Solution

The number of select lines required for an 8-line-to-1-line multiplexer is determined by the formula 2^n = m, where n is the number of select lines and m is the number of output lines.

In this case, we have 8 output lines, so we need to solve for n in the equation 2^n = 8.

If you calculate, you'll find that n = 3.

So, the correct answer is b. 3.
