I agree with Diego. Option D is the way to go. The `Number()` function ensures that the result is a numeric value, which is necessary for the division operation.

Option D is clearly the correct answer. The `Number()` function is used to convert the result of the expression `(num + 10)` to a number before dividing by 3.
