Quantum entanglement is a phenomenon in which two particles become correlated in such a way that measuring one instantly determines properties of the other, regardless of the distance between them. Einstein famously called this "spooky action at a distance" and remained skeptical. Modern experiments have repeatedly confirmed entanglement's existence, though it does not, as is sometimes claimed in popular accounts, allow information to travel faster than light.

Quantum entanglement is a confirmed correlation between distant particles, but it does not violate the speed of light, contrary to common claims.
- B
Einstein was wrong about everything.
- C
Entanglement allows faster-than-light communication.
- D
Most physicists doubt entanglement.
Explanation
The passage establishes entanglement as confirmed and corrects the FTL misconception — B. A is the misconception; C and D are unsupported.
