Suppose tangent of b is equal to negative 2 , and the terminal side of b is located in quadrant II. What is cotangent of b ?

Cotangent is the reciprocal of tangent. Since tan(b) = −2, cot(b) = 1/(−2) = −1/2, which is choice A, negative one half. This sign also fits quadrant II, where tangent and cotangent are negative.
