6. What is the basic principle of quantum entanglement?

Particles can be in multiple states simultaneously.

Particles can communicate faster than the speed of light.

Particles become interdependent and share correlated properties.

Particles can teleport instantly to a different location.

Quantum entanglement suggests that when two particles become entangled, their states become interdependent, and measuring the state of one particle instantly determines the state of the other, regardless of the distance between them.
