According to the Nyquist-Shannon sampling theorem, to prevent aliasing, the minimum sampling rate f_s must be:

AAt least twice the maximum message frequency (2 * f_max)
BHalf of the maximum message frequency (0.5 * f_max)
CEqual to the maximum message frequency (f_max)
DFour times the maximum message frequency (4 * f_max)

Explanation

Nyquist criteria states that sampling frequency f_s must satisfy f_s >= 2 * f_max to accurately reconstruct a bandlimited signal without aliasing.
