Answer:

Option B

Explanation:

The function is in the form A cos (bx)+c where A is the amplitude and B is the period. The amplitude of this function is 3 so that rules out option D. The formula for finding the period is 2pi/b so 2pi/pi/2 is 4 so that makes the period 4. The equation that matches the description is B
