Then in call by reference why do we write &&? I think option A is correct.

With the new standard (c++ 11) even the option 1 is correct.

& I known as (address of) operator. Which provides address of a variable.
Example 1:
Thus when we write,
int a;
scanf("%d",&a); This ,means we are taking the value to get stored in the (address of a).
Example 2:
int *a, b =10;
a = &b;
Similarly when we store a reference of a variable to a pointer, this means we are storing the address of that variable to a pointer.

A reference variable is created as follows.
Data-type & reference-name = variable-name.
Data-type & reference-name = variable-name.
