C - When assigning multiple IP addresses to a network interface using the command line tools or API, the entire operation fails if one of the IP addresses can't be assigned. https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/MultipleIP.html

Maybe D https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/using-eni.html#AvailableIpPerENI IP addresses per network interface per instance type The following table lists the maximum number of network interfaces per instance type, and the maximum number of private IPv4 addresses and IPv6 addresses per network interface. The limit for IPv6 addresses is separate from the limit for private IPv4 addresses per network interface. Not all instance types support IPv6 addressing.

maybe C, because the number of assigned IP is over limitation.
