A general chart could have a scale of __________.

Correct Answer: Option C — 1:200,000

Charts are categorized by scale: Sailing (1:600,000 and smaller), General (1:150,000 to 1:600,000), Coast (1:50,000 to 1:150,000), and Harbor (1:50,000 and larger). A scale of 1:200,000 falls within the General chart classification, which is used for coastal navigation when the vessel is well offshore but approaching the coast.
