A Correct answer
Explanation

Mean = (35 + 38 + 32 + 35) / 4 = 140 / 4 = 35.

AI explanation

The formula for the mean is the sum of all observations divided by the total number of observations. The sum of students across the four grades is 35 plus 38 plus 32 plus 35, which equals 140. Dividing this total by 4 gives the mean, so 140 divided by 4 equals 35.
