A group of projection with horizontal parallelsand evently set vertical meridians.

• A. Cylindrical projection
• B. Conic projection
• C. Planar projection
• D. Pseudo-cylindrical projection

Answer: (A)

The key idea is how a projection family shapes the grid of latitude and longitude on the map. In cylindrical projections, the sphere is projected onto a cylinder, so when you unroll it, lines of latitude (parallels) appear as horizontal straight lines and lines of longitude (meridians) appear as vertical straight lines. If the cylinder is chosen so the scale is uniform, these meridians are evenly spaced across the map, giving a grid with horizontal parallels and evenly set vertical meridians. This clean, regular grid is a hallmark of cylindrical projections and fits the description nicely.

Other projection types don’t produce that same grid: conic projections have parallels as circular arcs and meridians that converge toward a point, so the vertical lines aren’t evenly spaced; planar projections map onto a plane from a point, leading to a different grid structure; pseudocylindrical projections often have curved meridians or parallels, so you wouldn’t see strictly horizontal parallels with evenly spaced vertical lines.
