The passage implies that quantum mechanics differs from classical mechanics in its:

Quantum mechanics, a foundational theory in physics, describes the behavior of matter and energy at the atomic and subatomic levels. Unlike classical mechanics, which provides an accurate description of the macroscopic world, quantum mechanics introduces concepts like wave-particle duality and quantum entanglement, often defying intuitive understanding but proving incredibly accurate in its predictions.

1. A.Historical origins.
2. B.Applicability and theoretical principles.
3. C.Mathematical complexity.
4. D.Experimental verification.
