Explanation

Note: The exhibit and the distinguishing sub-configurations under each option (A, B, C, D) are not visible in your question - all four choices show only "router bgp 65005" with no additional lines. Without those details, a precise per-distractor explanation is impossible. Here is the concept-level explanation that applies regardless:

Why C is correct: The BGP Additional Paths (Add-Path) feature requires explicit receiver-side configuration. Option C is correct because it includes the commands needed to enable receiving and installing multiple paths - typically bgp additional-paths receive at the address-family level and/or neighbor <X> additional-paths receive per peer. Without these, Router 1 and Router 3 will silently ignore the extra paths Router 2 advertises, even if Router 2 is correctly configured as the sender.

Why the distractors fail: The wrong options likely omit the additional-paths receive command, use send instead of receive (configuring the wrong direction), or apply the command outside the correct address-family context, making it ineffective.

Memory tip: Think "sender sends, receiver must receive" - Add-Path is a two-sided handshake. Router 2 is the sender, so R1 and R3 must explicitly be configured as receivers. If you see a question about "installing all additional paths," look for additional-paths receive on the non-advertising routers.

If you can paste the full text of options A–D, I can give you a precise distractor-by-distractor breakdown.
