1) Please answer full question (a- e) All multiple choice. No work needed to be shown but ensure answer is correct for thumbs up.

a) Consider an 8x8 button keypad, which contains 64 buttons. What is the number of pins required using the concept of multiplexing?

b) Choose the primary benefit of using multiplexing in this Lab?

c) Select which argument will turn the pin number 24 in PIC microcontroller ON?

d) Consider the following code below:

e) Consider variable A = 0b1010 and variable B = 0b0101, what is the value of variable C when:

64 032 O8 16 O To reduce the number of needed pins on both input and output. o To output the correct value without involving the processor; that is, to allow the input to write to the output directly. O To perform operations that combine the input with the output.
