Explanation

ifconfig (interface configuration) is the classic Unix/Linux command for both configuring and deconfiguring network interfaces - running ifconfig eth0 down brings an interface down and removes its configuration. Options A (ipdown) and D (netdown) are fabricated commands that do not exist in any standard Linux distribution. Option B (net) is a Windows command-line utility for managing network shares and services, not a Linux interface tool - and even on Windows it cannot deconfigure a network interface in the way the question describes.

Memory tip: Think of ifconfig as the Swiss Army knife of interface management - the "if" stands for interface, and it handles both up and down operations. Modern systems also use ip link set eth0 down (from the iproute2 suite), so knowing ifconfig is the legacy answer while ip is the modern equivalent will serve you well on broader networking questions.
