When you project a globe’s parallels and meridians onto a cylinder and then unwrap, you’re using a cylindrical projection. A classic example arises from this method: the projection designed to preserve shapes locally and angles, useful for navigation, is built by mapping onto a cylinder and unwrapping. The Miller projection is a modified version of that cylinder-based approach, altering the latitude scaling to reduce distortion near the poles while staying rooted in the same cylinder method. This is why it’s considered derived from projecting onto a cylinder and unwrapping. The other options don’t follow this exact cylindrical construction: Gall is a pseudocylindrical projection with different geometry, Cassini is a different historical projection, and Mercator is the standard cylinder-derived form, with Miller serving as its variation.
