A. b/a = 2/5
True.
B. Since the ratio of a and b is positive, then they must be same sign.
So, product must also be positive. True.
C. If a = 5, b = 2. True.
Even if a = -5, b = -2. True.
D. Similar to A. True.
E. If a = 5, b = 2. True.
But if a = -5, b = -2, a-b is negative. False.
Hence, E is the answer.
True.
