Entanglement intuition

Why is entanglement considered special in quantum computing?

A

Entangled qubits explore every branch of the computation in parallel, one branch per copy

B

The full state of entangled qubits cannot always be described as independent individual states

C

Entangled qubits let a measurement on one send a chosen message to the other instantly

D

Entangled qubits can be copied freely because the correlation already duplicates the state
