Step 1. Analyze Statement-I: The definition of degenerate orbitals is accurate, as orbitals with the same energy level are indeed degenerate.
Step 2. Examine Statement-II: In a hydrogen atom, all orbitals in the same principal quantum level (e.g., 3s, 3p, 3d) are degenerate, as they have the same energy. Therefore, Statement-II is incorrect.
Step 3. Conclusion: Statement-I is correct, but Statement-II is incorrect.
