The circuit switches are used to provide a network that connects among the two parties, which are dedicated for the use to the parties for the length of the connection. It is a familiar technique, that is used to create a network for communication, which is used on telecalls. It also enables the hardware and circuits to share among the users, and for every user, it has direct access to the circuit during the use of the network.
Assuming the data was encrypted with YOUR public key, you'll need YOUR private key to decrypt it. That's answer e.
a and b are not solutions by themselves, of course you need to use the decryption algorithm, but a key goes with it.
c would be about symmetric encryption, but this is asymmetric, so different keys are used for encryption and decryption
d is possible, but it would mean anyone can decrypt it (after all the key is public), so then there's no point in encrypting it in the first place.
So e is the only logical answer.
