Assuming A and B are 32-bit signed integers, which of the following arithmetic operations can NEVER set the output signal V of the ALU (i.e., never cause an overflow)? Circle all that apply

a) A + B, where A > 0 and B > 0

b) A + B, where A < 0 and B < 0

c) A + B, where A > 0 and B < 0

d) A + B, where A < 0 and B > 0

e) A - B, where A > 0 and B > 0

f) A - B, where A < B and B < 0

g) A - B, where A > 0 and B < 0

h) A - B, where A < 0 and B > 0

i) none of above
