  C -> is the right answer here. The options B and D are restricted CIDR. You can see these restrictions here: https://docs.aws.amazon.com/vpc/latest/userguide/vpc-cidr-blocks.html

  I just tested it and got the following error messages: - Failed to add IPv4 CIDR: 10.0.0.0/16 The CIDR '10.0.0.0/16' is restricted. Use a CIDR from the same private address range as the current VPC CIDR, or use a publicly-routable CIDR. - Failed to add IPv4 CIDR: 192.168.0.0/16 The CIDR '192.168.0.0/16' is restricted. Use a CIDR from the same private address range as the current VPC CIDR, or use a publicly-routable CIDR.

  This question has two correct answers : B and D. You can only add non overlapping CIDR as additional cidr.
