Answer-first summary for fast verification
Answer: 10.0.0.0/8
The correct answer is **B (10.0.0.0/8)** because it allows for the maximum number of private IP addresses within a VPC, offering up to 16,777,212 available IPs. This is one of the standard private CIDR blocks recommended for VPCs. - **192.168.0.0/16** provides 65,532 IPs. - **172.16.0.0/12** offers 1,048,572 IPs. - **0.0.0.0/0** is not a valid RFC 1918 CIDR range for a VPC. Options A, C, and D are incorrect as they either provide fewer IPs or are not permissible for VPC configurations.
