A. the fifth layer
B. the second layer
C. the first layer
D. the seventh layer

Answer 1

Hopefully i am correct! Sorry if i am not

Step-by-step explanation:

Every transmission medium network function operates at the Physical Layer (Layer 1) of the OSI model.

The Physical Layer is responsible for the physical transmission of data over the communication channel, including the electrical, mechanical, and functional specifications of the network interface, such as voltage levels, data rates, and physical connectors.

Therefore, the correct answer is C. the first layer.
