Secant is a trigonometric function that is the reciprocal of the function cosine. This means that in a cartesian plane, the value of secant is equal to r / x. For the values to be undefined, x should be zero. The angles are π/2 and 3π/2. The answers are B and D.

8/1 : 1/5 = 8/1*5/1 = 40/1 = 40
Another method :
1/5 = 0.2
8/0.2 = 40
The answer is C, since the number in the parenthesis represent what is being multiplied every year
