choose the most appropriate name for the function described below

the sweetness of the cake depends on the amount sugar in it.
A. amount(sweetness), or a(s)
B. amount(cake), or a(c)
C. cake(amount), or c(a)
D. sweetness(amount), or s(a)

D. sweetness(amount), or s(a)

D. sweetness(amount), or s(a)

The most appropriate name for the function described, where the sweetness of the cake depends on the amount of sugar in it, would be D. sweetness(amount), or s(a).

In this case, the function name should reflect what the function is doing - determining the sweetness based on the amount of sugar. Therefore, "sweetness" should be the first part of the function name to indicate that it calculates the sweetness. The second part, "amount", should be included to convey that the function takes an amount of sugar as input. The notation s(a) represents the function name with "s" representing sweetness and "a" representing the amount.
