Which instruction should exist on line 1 in the MIPS code below to correctly implement the provided C program? Note: Assume register $t0 represents variable a and register $t1 contains the value 100. C Program int a = 0; if(a 100) a++; else a = 0; MIPS Code 1 2 else: add $to, $zero, $zero 3 if: addi $t0,$t0, 1 beg $t0,$t1, if bne $t0,$t1, if bne $t0,$t1, else Not possible using a single MIPS instruction
