Solution

The correct answer is c. addi 2,2, 1, 10.

Here's the step by step explanation:

The addi instruction in MIPS assembly language adds a register and a constant. The format is addi destination,destination, source, constant. The result is stored in the destination register.

a. addi 1,1, 2, 10: This adds the value in 2(6)to10andstorestheresultin2 (6) to 10 and stores the result in 1. This is not the correct answer because we want the result in $2.

b. addi 1,1, 2, 0x10: This adds the value in 2(6)to0x10(16inhexadecimal)andstorestheresultin2 (6) to 0x10 (16 in hexadecimal) and stores the result in 1. Again, this is not the correct answer because we want the result in $2.

c. addi 2,2, 1, 10: This adds the value in 1(10)to10andstorestheresultin1 (10) to 10 and stores the result in 2. This gives us the desired result of 26 in $2.

d. addi 2,2, 1, 0x10: This adds the value in 1(10)to0x10(16inhexadecimal)andstorestheresultin1 (10) to 0x10 (16 in hexadecimal) and stores the result in 2. This would result in a value of 26 in 2ifthevaluein2 if the value in 1 was 10, but the value in $1 is not 10, so this is not the correct answer.
