Time left 1:08:51 Assume A is an array and x is a variable. A and x are associated to registers $50 and $to respectively. Which of the following C++ code is equivalent to: addi $t1,$t0, 2 sll $t1,$t1, 2 add $S1, $50, $t1 lw $t3, O($S1) sw $t3, 12($50) 7 Select one: O A[3]=A[2+x]; O A[12]=A[2+x]; O A[3]=A[4+x]; O A[2+x]=A[3]; O A[12]=A[4+x]; e to search TO W
