Triangle PQR is a right triangle, So are triangle PQT and triangle QRT (where T is perpendicular to Q on line / diameter a-b)
Statement (1) gives a = 4. Since 2 is proportion to 4, then b = 1/2 * 2 = 1. Thus, a = 4, b = 1. a+b = 5. Sufficient. Eliminate B,C,E.
Statement (2) gives b = 1. Since b is proportion to 2, then a = 2 * 2 = 4. a+b = 5. Sufficient. Eliminate A.
Ans: D.

Jimmy bear with me as I try grasping the concept.
Can you go into the elements of these statements please :
Statement (1) gives a = 4. Since 2 is proportion to 4, then b = 1/2 * 2 = 1. Thus, a = 4, b = 1. a+b = 5. Sufficient. Eliminate B,C,E.
Statement (2) gives b = 1. Since b is proportion to 2, then a = 2 * 2 = 4. a+b = 5. Sufficient. Eliminate A.
