Correct answer: B
To parse the declaration int(*p[5])(), start with the identifier p. The brackets [5] indicate that p is an array of 5 elements. The parentheses around *p[5] override the default precedence, meaning each element of the array is a pointer. Finally, the trailing () indicates that these pointers point to functions returning an integer. Thus, p is an array of 5 pointers to functions that return int.
