float *(*ptr)(int*); is implicitly converted into ptr*(int*)float* which means that ptr is pointer to a function, which receives int pointer and returns float pointer.

@Mohini : What will you do if there is one more option with 3 *s ?

Simple answer i.e. function declared as pointer function which receives integer type pointer as argument and returns float type pointer.

(int*)= specifies that it receives an input pointer.
(*ptr)(int*)= it specifies that it is a pointer to function which receives integer pointer.
float *(*ptr)(int*)= this specifies that it returns float pointer.
(*ptr)(int*)= it specifies that it is a pointer to function which receives integer pointer.
float *(*ptr)(int*)= this specifies that it returns float pointer.

Simple trick: 'Pointer' word is used 3 times. So somehow manage to get * three times in your answer.
