Solution

The correct option is D
(d) P → r; Q → p; R → q

The explanation for the correct answer
1. When an apple falls down downward force is acting on it which is unbalanced. Therefore, (Q) matches with (p).
2. Book is not moving, Hence, the force acting on it is due to gravity and normal balance with each other. Therefore, (P) matches with (r).
3. Frictional force act only when two bodies are in contact with each other. Therefore, (R) matches with (q)
Hence the correct option is (D)
