Passage: "The concept of 'quantum entanglement' describes a phenomenon where two or more particles become linked in such a way that they share the same quantum state, regardless of the distance separating them. When one entangled particle is measured, its properties (such as spin or polarization) instantaneously determine the properties of its entangled partner, even if they are light-years apart. This 'spooky action at a distance,' as Einstein famously called it, appears to violate the principle of locality, which states that an object is only directly influenced by its immediate surroundings. However, entanglement does not allow for faster-than-light communication, as no information can be transmitted faster than light, only shared states. The full implications of entanglement are still being explored, but it is a cornerstone of quantum computing and cryptography." The author's primary purpose in discussing Einstein's phrase 'spooky action at a distance' is to:

1. ACriticize Einstein's understanding of quantum mechanics.
2. BExplain how entanglement allows for faster-than-light communication.
3. CHighlight the counter-intuitive nature of quantum entanglement.
4. DIntroduce a historical anecdote to make the passage more engaging.
