Explanation

The requirements-loop detection/prevention, automatic port configuration, and use of a standard (non-proprietary) protocol-all point to STP (Spanning Tree Protocol) and its modern variant RSTP (Rapid STP, IEEE 802.1w). STP/RSTP is an IEEE standard (802.1D) that detects and eliminates Layer 2 switching loops by placing redundant ports into a blocking state. RSTP also introduces automatic port role negotiation, fulfilling the 'automatic port configuration' requirement. SIP (B) is the Session Initiation Protocol used for VoIP signaling and has nothing to do with network loops. RTSP (C) is the Real Time Streaming Protocol for media streaming. BGP (D) is the Border Gateway Protocol used for inter-AS routing on the internet and does not address Layer 2 loop prevention.
