Explanation

Graceful-restart (A) allows a BGP router to maintain forwarding during a control-plane restart, so traffic continues flowing while BGP reconverges - directly minimizing data loss. BFD (C) (Bidirectional Forwarding Detection) provides sub-second failure detection on links, enabling BGP to react far faster than its native hold-down timers, which reduces the window where traffic is lost on a redundant path.

ibgp-multipath (B) enables load-balancing across multiple iBGP paths within the same AS - it doesn't apply here because the question specifies two separate autonomous systems (eBGP), and it doesn't address resiliency or data loss minimization directly. route-reflector-client (D) is an iBGP scaling mechanism used to eliminate full-mesh requirements inside a single AS - again irrelevant to an inter-AS (eBGP) resiliency scenario.

Memory tip: Think "GracefulBFD = No Data Dead" - Graceful-restart keeps forwarding alive during restarts, BFD detects failures fast. Together they cover the two failure scenarios that cause data loss: planned restarts and unplanned link drops.
