### Question 13

The flowchart below presents the tasks involved in binary number multiplication through repeated shift operations and additions. Which of the following answers is the correct combination of processes a and b in this flowchart? In this example, multipliers and
multiplicands are expressed as 16 bits without signs. X, Y and Z are 32-bit registers, and logical shifting is used for shifting. a b a) Least significant bit in Y Shift X one bit to the left and Y one bit tothe right. b) Least significant bit in Y Shift X one bit to the right and Y one bitto the left. c) Most significant bit in Y Shift X one bit to the left and Y one bit tothe right. d) Most significant bit in Y Shift X one bit to the right and Y one bit tothe left.
