p=&i;
(ii) int *p;
p=&p;
//
both cases are possible i hope now u understand wt a pointer is

The answer can be summarized as follows...

[A] A keyword used to create variables -> Wrong. A pointer is NOT a keyword.
[B]. A variable that stores address of an instruction -> Wrong. Though a pointer may hold the address of an instruction (i.e. function pointer), it is no required to
[C]. A variable that stores address of other variable -> Correct. A pointer is a variable that stores the address of any other variable be it a value or another address.
[D]. All of the above -> Wrong as A and B are incorrect.

Pointer is a generic term which means "pointing to something".We can use pointer to store address of any variable or any function (Function pointer).
"Program Counter also known as instruction pointer (IP) in Intel x86 holds the address of instruction."

A pointer store the address of the another variable.

A pointer is used to store the address of another variable.
