What does VRM stand for?

Explanation:
The concept tested is radar terminology and how distance is measured on the radar display. A Variable Range Marker is an adjustable marker on the radar screen that lets you set a specific distance from your own vessel. By moving this marker to align with a target, you can read off the distance from the scale, giving you the target’s range. This tool is often used together with Electronic Bearing Lines to determine position by both range and bearing. The other terms aren’t standard radar jargon. Visual Range Marker would imply a marker tied to visual sighting rather than radar, and Virtual Range Marker or Velocity Range Marker aren’t common terms in navigation radar.
