        **What are UDP Socket Level Options?**

        UDP socket level options allow configuration of various socket behaviors like timeout, buffer size, and multicast settings for UDP communication.

        **How do UDP Socket Level Options work?**

        Options are set using system calls like `setsockopt()` and control parameters such as send/receive buffer sizes, time-to-live (TTL), and multicast group membership.
