Step 1: Understanding polar region projections.
- Azimuthal Projection: Used for polar regions as it accurately represents circular areas.
- Conic Projection: Suitable for mid-latitudes but not for poles.
- Oblique Projection: Used for tilted perspectives, not for poles.
- Cylindrical Projection: Distorts poles, making it unsuitable.
Step 2: Selecting the correct option.
Since Azimuthal projection is most accurate for polar regions, the correct answer is a. Azimuthal.
