Which projection group is described as having horizontal parallels and evenly spaced vertical meridians?

Explanation:
In cylindrical projections, the sphere is wrapped onto a cylinder and then unwrapped to a rectangle. Longitudes map to vertical lines and latitudes map to horizontal lines. In the common rectangular form, the grid is uniform, so the vertical meridians are evenly spaced while the parallels appear as horizontal lines. This combination—horizontal parallels with evenly spaced vertical meridians—characterizes cylindrical projections. Other families form different grid patterns (cones or radial circles) and don’t produce that same straight, regularly spaced grid.
