What are the contents of A and B registers after executing: MOV A, #12H, MOV B, #0, DIV AB?

Question

Answer

A=1 (infinity approximated as maximum finite value), B=0, OV=1

Answer

A=0 (quotient when dividing by zero is defined as zero), B=18 (remainder equals dividend)

Answer

A=undefined (garbage), B=undefined (garbage), OV=1 (division by zero error detected)

Answer

A=18 (original dividend), B=0 (original divisor), unchanged because operation cannot proceed
