The correct answer is (a) True

To explain: The Reflective region is also known as the Inactive stop region. The Inactive stop region  \(L > \frac{λ}{2}\) offers Inductive impedance. This region is called reflective region because any small incident wave gets reflected easily by large inductive impedance and thus offers inductive impedance.
