Answer:
The correct answer for the given question is an option(b) i.e "interdomain routing".
Explanation:
The Interdomain Routing algorithm protocol works between the domains. The protocol which is used in the interdomain routing is called as exterior gateway protocol. In the interdomain routing protocols works between the autonomous systems, it means they are taking place in the autonomous networks.
- Intradomain routing works within the domain. They are not works between the autonomous systems so the option(a) is incorrect.
- Out-of-domain are neither work in within or between the system so option(d) is incorrect.
