When x = 1, y = 1 + 4 = 5

When x = 3, y = 3 + 4 = 7
When x = 5, y = 5 + 4 = 9
When x = 7, y = 7 + 4 = 11

Therefore, the correct answer is option D.

y = x + 4

A. (1, 4), (2, 6), and (3, 7)
4 = 1 + 4 ------------> not equal

B. (1, 4), (2, 8), and (3, 12)
4 = 1 + 4 ------------> not equal

C. (3, 7), (5, 9), and (7, 10)
7 = 3+4 = 7
9 = 5+4 = 9
10 = 7+4 = 11 ------> not equal
D. (3, 7), (5, 9), and (7, 11)
7 = 3+4 = 7
9 = 5+4 = 9
11 = 7+4 = 11

Therefore, the correct answer is option D.
