The modulus operator cannot be used with a long double.

[A]. True
[B]. False

Answer: Option A


fmod(x,y) - Calculates x modulo y, the remainder of x/y.
This function is the same as the modulus operator. But fmod() performs floating point or long double divisions.

example for fmod:
int main()
float x=10.10,y=2.0, z;
printf("%f", z);

return 0;

Is this means that modulus operator works ONLY on integers?

It is not possible to perform modulo operator with float and double.

If I am right, fmod(x,y) is a function. And the question is "The modulus operator cannot be used with a long double". Then the answer should be (B). Because we can not use modulus operator with float or double. For this, we use the function in math.h header file which is fmod().

I think the answer is B.
