okay! and also in question, what they are trying to say by physical transmission (i just get confused it with Manchester & differential Manchester encoding).
Use of "physical transmission" focuses on the fact that eventually data is transmitted over wires. Only "transmission" would also solve the purpose of the question.

The OSI (Open Systems Interconnection) Reference model has 7 layers. Namely-

  • Physical Layer
  • Data Link Layer
  • Network Layer
  • Transport Layer
  • Session Layer
  • Presentation Layer
  • Application Layer

The Presentation Layer providing services that allow communicating applications to interpret the meaning of data exchanged.This services include data compression and as well as data encryption

$\color{green}{\text{Presentation Layer}}$ $\text{will be the answer}.$
