take place?
A.
Application
B.
Transport
C.
Session
D.
Presentation
Presentation
Explanation: https://en.wikipedia.org/wiki/Presentation_layer
In the seven-layer OSI model of computer networking, the presentation layer is layer 6 and
serves as the data translator for the network. It is sometimes called the syntax layer. The
presentation layer is responsible for the formatting and delivery of information to the
application layer for further processing or display.
Encryption is typically done at this level too, although it can be done on the application,
session, transport, or network layers, each having its own advantages and disadvantages.
Decryption is also handled at the presentation layer. For example, when logging on to bank
account sites the presentation layer will decrypt the data as it is received.
