A student was finding the solutions to the equation 1 + sqrt(x - 3) = 0 and wrote the four steps shown.

Step 1: sqrt(x - 3) = - 1
Step 2: (sqrt(x - 3)) ^ 2 = (- 1) ^ 2
Step 3: x - 3 = 1 1
Step 4: x = 4

Which statement is an accurate interpretation of the student's work?

A. The student made an error in Step 1.
B. The student made an error in Step 3.
C. The student found the correct solution to the original equation , x = 4.
D. x = 4 is a solution to the equation in Step 2, but not to the original equation .
