Answer: 2 & 2/4 which is choice A

Work Shown:

1/4 = 0.25

2/4 = 0.5

3/4 = 0.75

2 & 3/4 = 2 + 3/4 = 2 + 0.75 = 2.75

5 & 1/4 = 5 + 1/4 = 5 + 0.25 = 5.25

Subtract the values:

5.25 - 2.75 = 2.5

Then convert back to a mixed number

2.5 = 2 + 0.5 = 2 + 2/4 = 2 & 2/4

Optionally you can reduce that 2/4 into 1/2, but it appears your teacher has chosen not to.
