A public key encryption system
(A) allows anyone to decode the transmissions
(B) allows only the correct sender to decode the data
(C) allows only the correct receiver to decode the data
(D) does not encode the data before transmitting it

Answer: (C)
Explanation: Public-key encryption is a cryptographic system that uses two keys, a public key known to everyone and a private or secret key known only to the recipient of the message.
A receiver can decode the message using his own private key and the public key of the sender.
