Which principle is responsible to ensure that quantum information is secured from unauthorized replication?

Correct option is A

​$$\text{The no-cloning theorem in quantum mechanics states that it is impossible to create an identical copy of an arbitrary unknown quantum state.} \\[8pt]\text{This principle ensures security in quantum communication and quantum cryptography, because:} \\[6pt]\bullet \ \text{Any attempt to copy (replicate) quantum information will disturb the state.} \\[4pt]\bullet \ \text{Such disturbance can be detected, preventing unauthorized replication.}$$​​
