I agree, Option D is the clear winner. Using 'Number()' is the best way to convert the expression to a numeric value before the division.

Haha, 'Integer(num +10) /3' - that's just asking for trouble! Definitely go with D, the 'Number()' function is the way to go here.

Yeah, D is the safest choice. 'Integer()' could lead to unexpected results.

I'm not sure about the other options, but D seems the most straightforward way to ensure the result is a number. The 'Number()' function should do the trick.

Option D looks good to me. It seems to directly apply the 'Number()' function to the expression 'num + 10' before dividing by 3.

Because we need to ensure that the result is a number, so we should use Number() to convert it.
