Which projection is a conical projection used for predominantly NS orientation?

• A. Polyconic Projection
• B. Gnomonic Projection
• C. Lambert Conformal Projection
• D. Stereographic Projection

Answer: (C)

Conic projections are designed to minimize distortion for regions that have a particular directional extent. When a map area is tall and runs primarily north–south, a conic approach that preserves shapes locally is especially helpful, because the projection can be tuned to keep angles accurate along the lines that matter most. The Lambert Conformal Conic projection does exactly this: it’s conformal, meaning it preserves local shapes and angles, and it uses two standard parallels where the scale is true. By choosing those standard parallels to bracket the region’s north–south extent, distortion is minimized along that tall orientation, making it well suited for predominantly NS-focused areas. The other options don’t fit as well: gnomonic and stereographic are not conic projections, and while Polyconic is a conic option, it doesn’t provide the same reliable shape preservation and standard-parallel framework that Lambert Conformal Conic offers for regions oriented north–south.
