(Multiplexer Logic) You are asked to implement the function:

using a 4:1 multiplexer and as much other logic as you need, but you want to minimize that extra logic. Which two signals should you use to control the multiplexer? Implement the function using a multiplexer controlled by the following combinations of input signals. Which ends up requiring the least logic? Why?

(a) Use A and B as control inputs to the 4:1 multiplexer

---

(b) Use B and C as control inputs to the 4:1 multiplexer

---

(c) Use B and D as control inputs to the 4:1 multiplexer

---

(d) Use C and D as control inputs to the 4:1 multiplexer
