Which term describes 'Narrow gauge multiple track'?

• A. Narrow gauge multiple track
• B. Standard gauge multiple track
• C. Standard gauge single track
• D. Railroad in street

Answer: (A)

Understanding gauge and how many tracks a railroad has helps decode this phrase. Gauge is the distance between the rails, and “narrow gauge” means that distance is smaller than standard. “Multiple track” means there are two or more parallel tracks, allowing trains to operate in more than one lane at the same time. So the term that best fits the description “Narrow gauge multiple track” is the phrase itself, because it exactly conveys a railroad with a narrower-than-standard gauge and more than one track side by side.

The other options change part of the idea: standard gauge multiple track would describe many tracks but with standard gauge, not narrow; standard gauge single track would have one track with standard gauge; and railroad in street describes a street-running railroad scenario, focusing on location rather than gauge or track count.
