The correct option from the following statements is:
Statement 1: Binding energy per nucleon is higher for heavy nuclei \((A > 170)\).
Statement 2: Binding energy per nucleon is lower for light nuclei \((A < 30)\).
Statement 3: Binding energy per nucleon in the range \(30 < A < 170\) is nearly constant since nuclear force is strong and short-ranged.
Statement 4: Binding energy per nucleon is higher for both light nuclei \((A < 30)\) and heavy nuclei \((A > 170)\).
