Explanation

The best strategy here is to assume values of a and b.

Let a = 1 and b =2 .

Quantity A: $$\frac{1}{2}$$
Quantity B: $$\frac{1+3}{2+3}=\frac{4}{5}$$

Quantity B is greater.

Let a = 6 and b=3
Quantity A: $$\frac{6}{3}=2$$
Quantity B: $$\frac{6+3}{3+3}=\frac{3}{2}$$

Quantity A is greater.

Hence a relationship cannot be determined. Thus option D is correct.

Quantity A: $$\frac{6}{3}=2$$
Quantity B: $$\frac{6+3}{3+3}=\frac{3}{2}$$

Quantity A is greater.

Just wanted to say that 0 is not a positive integer. 0 is neither positive nor negative,
