Answer:

C. undefined

Explanation:

The cotangent function is defined as the ratio of the cosine and sine functions:

cot(x) = cos(x) / sin(x)

When x = π/2, sin(π/2) = 1 and cos(π/2) = 0, so we have:

cot(π/2) = cos(π/2) / sin(π/2) = 0/1

Division by zero is undefined in mathematics. Therefore, cot(π/2) is undefined.
