malloc and calloc return pointers to the heap, of type void $*.$ Why don't they return the type that you requested?

A: They can't, since C does not have support for functions that return multiple different types.

B: They could, but they don't for performance reasons.

C: They can't, since there's no way to return pointers to functions, and you might want to allocate a function.

D: They could, but it would make the API more awkward since you would have to pass the desired type as a parameter.
