The Transport layer on the recipient machine requests a retr

The Transport layer on the recipient machine requests a retransmission of a segment from the sending machine. This is an example of:

A. Same-layer interaction

B. Adjacent-layer interaction

C. Cross-layer interaction

D. Split-layer interaction

Solution

a layer on one machine which is communicating directly with the same layer on another machine is known as samelayer interaction.

c and d does not applicable to this scenario.

b interact with below are above stacks

So the final solution is A) same-layer interaction
