Answer:

b. 2Hz

Explanation:

Frequency is defined as the number of wavelengths passing a particular point per second.

If 3 crests pass a point in two seconds, then we know that 6 crests pass the point per second.

Therefore 2 wavelengths pass the point per second, and hence the frequency of the wave is 2Hz.
