I think that option B is correct because the overloaded function should be varied in type and number of argument, in that case, if we declare a function with default argument, the compiler gets confused to execute the correct function.

But say there are 2 functions one has one argument and other has 2 arguments and if I keep parameters blank while calling this function which one should be called as default arguments are defined in both of them?

@Pradhnya.
Only option c is correct answer because it says//*All arguments of an overloaded function "CAN BE " default*// means that It does not matter weather the parameter is default or not.

That means the answer is incorrect, because when we call the function, it is differentiated by the different argument type, that is only overloading.
Can someone give a reason?

include<stdio.h>
int main ()
{
int a;
int b;
printf("please enter the number a&b");
scanf(%d,%d:&a and &b);
return0;
}
int main ()
{
int a;
int b;
printf("please enter the number a&b");
scanf(%d,%d:&a and &b);
return0;
}

void fun(int a=10,int b=20);
void fun();
main()
{
fun();
}
Error will occur because redeclaration of function is type mismatch.
void fun();
main()
{
fun();

the parameters will be changed but not the functionality and the arguments in the function .

Ambiguous situation so error.
