D (Concept presentation) is usually too early and conceptual for detailed security input.

The classic "fire triangle" describes the three elements necessary for fire to occur:
Heat - to raise material to ignition temperature
Fuel - combustible material
Oxygen - typically from the air, to sustain combustion
Removing any one of these three elements will prevent or extinguish a fire.

Physical security refers to measures taken to protect personnel, equipment, and property from threats such as theft, vandalism, and natural disasters. This includes the use of locks, barriers, surveillance systems, access controls, and emergency response planning. It is a foundational element of organizational security strategy.

The Internet Protocol (IP) is used to route packets of data between LANs and WANs. It allows communication across interconnected networks regardless of the underlying hardware or local network configuration. IP is part of the TCP/IP protocol suite and is the foundational protocol for all modern internetworking.
Ethernet Protocol (A) applies to LANs but not internetwork communication.
Options B and C are not valid or recognized protocol names.
