Solution

The correct option is B
It is the length of the adjacent side divided by the length of the opposite side

The value of cotangent of an angle in a right angle triangle is the length of the adjacent side divided by the length of the opposite side. In triangle ABC, cotangent of angle A = $\frac{A B}{B C}$

AB = adjacent side

BC = opposite side, hence cot A = $\frac{A B}{B C}$
