Q1:

To completely load and then unload an 8-bit register requires how many clock pulses?

A 2

B 4

C 8

D 16

ANS:D - 16

The register can store 1bit information.

Here it has 8 Registers.
So to store 8 bit of information it requires 8 clock pulses.
However, to make zero the same data it again requires the same clock pulse viz 8.
So, the Total = 8 + 8 = 16.
