Answer:

B

Step-by-step explanation:

If a sinusoidal function is given in the form y = B Sin x or y = B Cos x, then,

B is called the amplitude of the function. It will define minimum and maximum.

The minimum & maximum of this form of a cos function is B and -B.

The function given is y = 7 Cos x, so the Maximum is 7 and Minimum is -7

Correct answer is B.
