What does PRCS stand for?

• A. Portable Remote Command System
• B. Public Resource Control Station
• C. Portable Remote Control Station
• D. Primary Remote Control Service

Answer: (D)

PRCS stands for Primary Remote Control Service. This four-word phrase fits the common pattern for describing a main functionality that directs operations from a distance as an ongoing service. “Primary” indicates the main or initial service, “Remote” shows it operates remotely, “Control” is the action of directing operations, and “Service” denotes a functional offering within the system. The other options change one term to a different meaning—portable suggests mobility rather than central importance, public resource doesn’t align with remote control concepts, remote command uses a different word for the action, and system instead of service alters the nature of what’s being described.
