You can enable or disable route propagation.

In a Virtual Private Cloud (VPC) environment, you can establish a Virtual Private Network ( VPN) connection between your VPC and your remote network. After establishing a VPN connection, you need to update your VPC route tables with the routes to your remote network.
Route propagation is a feature that automatically propagates routes from your VPN connection to your VPC route tables. When you enable route propagation, Amazon Web Services (AWS) automatically adds routes to the destination IP ranges in the VPN connection to the route tables in your VPC. This eliminates the need for you to manually enter VPN routes in your route table.
Peer routing is not a valid AWS feature. It may refer to routing between peers in a peer-to-peer network, but it is not relevant to VPN connections in a VPC environment.
Route navigation is not a valid AWS feature. It may refer to navigation of routes in a routing table, but it is not relevant to VPN connections in a VPC environment.
Route prepending is a technique used in Border Gateway Protocol (BGP) to manipulate the path selection of traffic. It is not a feature that negates the need for manually entering VPN routes in your route table.
Therefore, the correct answer is B. Route Propagation.
