The first derivative of a function f(x) is zero at some point, the second derivative is also zero at this point. This means that:

A. f has necessarily a minimum at this point
B. f has necessarily a maximum at this point
C. f has necessarily neither a minimum nor a maximum at this point
D. f might have either a minimum or a maximum or neither of them at this point
