Selected Answer: A
The Originator ID is not used to control BGP route selection. The Originator ID is a BGP attribute that is used to prevent routing information loops within a single BGP Autonomous System (AS) when Route Reflectors (RRs) are deployed. It helps avoid the reflection of routes back to the originator router. However, it is not involved in the process of BGP route selection or influencing the best path selection process.

Prefers the route advertised by the device with the smallest router ID. If a route carries the Originator_ID attribute, BGP prefers the route with the smallest Originator_ID without comparing the router ID. https://support.huawei.com/enterprise/en/doc/EDOC1100034072/2a827a34/bgp-route-selection-rules-and-load-balancing
