Which symbol is used for political boundary surveys?

• A. Pbs
• B. Pb
• C. Pcc
• D. Pcs

Answer: (B)

Political boundaries are the borders between sovereign jurisdictions, and maps use a distinct shorthand to mark them so readers recognize the type at a glance. The symbol that represents a political boundary is the abbreviation that stands for Political boundary. This two-letter code is preferred because it cleanly signals this specific kind of boundary without implying other boundary categories.

The other options include extra letters that would suggest different kinds of boundaries or features, so they don’t convey the standard meaning of a political boundary on survey maps.
