D Correct answer
Explanation

In 2016, boys in school D = 6.4 (hundreds). In 2017, boys in school D = 5.3 (hundreds). The decrease is 6.4 - 5.3 = 1.1. The percentage decrease is (1.1 / 6.4) * 100 = 17.18%, which is approximately 17%.

AI explanation

From the table, the number of boys in school D in 2016 was 640 and in 2017 was 530. Using the percentage decrease formula, we calculate the difference as 640 minus 530, which equals 110. Dividing 110 by 640 gives 0.1718, and multiplying by 100 yields an approximate percentage decrease of 17%.
