Is x an even integer?

A Statement (1) ALONE is sufficient, but statement (2) ALONE is not sufficient.
B Statement (2) ALONE is sufficient, but statement (1) ALONE is not sufficient.
C BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.
D EACH statement ALONE is sufficient.

✓ Correct Answer: Option D

If x² is even, x must be even. If (x+1)² is odd, then (x+1) must be odd, meaning x must be even. Both statements individually prove x is an even integer.
