Answer: A

Explanation:

Classless Inter-Domain Routing (CIDR) is a technique used to allocate and manage IP addresses more efficiently. It involves using variable-length subnet masks (VLSMs), which allow the network to have subnets of different sizes. VLSMs provide flexibility in allocating IP addresses by allowing the network administrator to choose the appropriate number of network and host bits based on the network requirements.
