If you want to receive a pointer then you can us a symbol " * ";

and if you want to return a pointer then you can us a symbol " * ";.

So as per our question that is "receives a "pointer to pointer to a pointer to a float".

We can use "float***"and same for function.

From the given question,

"... receives a pointer to pointer to a pointer to a float... " = ***

"... returns a pointer to a pointer to a pointer to a pointer..." = ****

Therefore, float ****fun (float ***) is the correct answer.
