Answer 2

Answer:

The correct option here is (c) Both i.e. both routing and error control.

Explanation:

There are 5 layers in networking in the OSI model. These are as follows:

1. Physical layer
2. Data link layer
3. Network layer
4. Transport layer
5. Session layer
6. Presentation layer
7. Application layer

The network layer is the third layer of the OSI model. It is responsible for both routing packets and error control.

Therefore, the correct option here is (c) Both i.e. both routing and error control.
