Two statements are given-one labelled Assertion (A) and the other labelled Reason (R). Select the correct answer to these questions from the codes (A), (B), (C), and (B) as given below.

Assertion (A): The curve between the binding energy per nucleon versus mass number droops at high mass numbers $(A > 170)$ as well as at low mass numbers $(A < 30)$ .

Reason (R): Nuclei with middle mass numbers $(30 < A < 170)$ have higher binding energy per nucleon.
