Explanation

The hosts file maps hostnames to IP addresses and is read by the OS resolver. After editing it, the local DNS cache may still hold stale entries from before the change. Among the given options, resetting the network adapter (D) clears the DNS resolver cache as part of resetting the network stack, causing the new hosts file entries to take effect. The ideal standalone fix would be 'ipconfig /flushdns', but that option is not available here. Clearing the browser cache (B) only affects the browser's own cache, not the OS-level DNS cache. Promiscuous mode (A) and adding a network adapter (C) are entirely unrelated.
