B Correct answer
Explanation

CIDR (Classless Inter-Domain Routing) allows route aggregation by using variable-length subnet masking. This enables network administrators to combine multiple contiguous subnets into single routing table entries, significantly reducing table size. Classful routing maintains separate entries for each network boundary.
