The incorrect work of a student to solve an equation 2(y + 8) = 4y is shown below:
Step 1: 2(y + 8) = 4y
Step 2: 2y + 10 = 4y
Step 3: 2y = 10
Step 4: y = 5
Which of the following explains how to correct Step 2 and shows the correct value of y? (5 points)
A: The equation should be y + 8 = 4y after division by 2; y = 4
B: The equation should be y + 8 = 4y after division by 2; y = 6
C: 2 should be distributed as 2y + 16; y = 4
D: 2 should be distributed as 2y + 16; y = 8
