A. B. C. D.Answer - C.
This is given in the AWS documentation.
The Elastic Network Adapter (ENA) supports network speeds of up to 25 Gbps for supported instance types.

http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/enhanced-networking.htmlThe option that provides network speeds of up to 25 Gbps for supported instance types is the Elastic Network Adapter (ENA).
Explanation: The Elastic Network Adapter is a network interface that provides high bandwidth and low latency network performance for EC2 instances. It is designed to provide up to 100 Gbps network speeds and reduce the network jitter and latency for enhanced performance.
In contrast, the Intel 82599 Virtual Function (VF) interface is a hardware device that provides virtualization support to improve network performance but does not offer 25 Gbps network speeds.
Route propagation is a mechanism used to propagate routing information between VPCs and on-premises networks through VPN or Direct Connect. However, it does not affect network speeds or provide high-performance networking capabilities.
VPC peering is a mechanism to connect two VPCs and enable them to communicate with each other privately, but it does not provide high bandwidth network speeds.
Therefore, the correct answer is option C, Elastic Network Adapter.
