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();
}

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?

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.

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

Option c is correct. It is not a matter weather the parameter is default or not!

The trailing arguments of the function can have default arguments.

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?

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;
}
