Neat lines on a quadrangle map refer to:

Neat lines on a quadrangle map refer to:

• A. The boundaries of quadrangle maps
• B. The inner grid lines
• C. The map's legend
• D. The scale bar

Answer: (A)

Neat lines define the outer boundary of a quadrangle map, forming the frame that encloses the mapped area. This boundary marks the exact extent of the sheet and helps ensure adjacent quadrangles line up cleanly when the maps are laid out together. The inner grid lines show coordinates inside the map, the legend explains symbols, and the scale bar gives distance; those features sit inside the neat line, not at its edge.
