The correct answer is D. To examine and compare population densities using one view of the entire world I would use the Robinson Projection.
Explanation:
Robinson Projection is a non-equivalent projection based on coordinates and not on mathematical formulation, having been designed to minimize angular and area distortions. In this projection the latitude parallels are straight, but the longitude meridians are not. The advantage of the Robinson projection is that it looks very natural. It shows relatively large deviations in angle and area only in the area of the poles, which increase with the distance from the central meridian. However, it is not distortion-free in any area.
