Answer:
D
Step-by-step explanation:
The answer is D. 32°E, 25°S.
Let's break it down:
- A map with the designation "3225BB" has two parts:
1) The first two numbers indicate the latitude parallel used: 32°
Since it starts with 32, that means the parallel must be 32 degrees. The two options are 32°N or 32°S.
2) The second two numbers indicate the longitude meridian used: 25°
Since it starts with 25, the meridian must be 25 degrees. The two options are 25°E or 25°W.
- The "BB" at the end indicates both lower case letters. By convention, this signifies south latitude and east longitude.
So putting this all together, we can deduce that:
- The latitude parallel used was 32°S (option A is incorrect)
- The longitude meridian used was 25°E (options C is incorrect)
Therefore, the correct answer is D: 32°E, 25°S

Here are some additional details about map projections:
Map Projections
Maps are 2D representations of the 3D surface of the Earth. To accomplish this, mapmakers use mathematical projections that transform the sphere into a flat surface.
There are several common types of map projections:
• Cylindrical: The globe is visualized as if it were wrapped around a cylinder. This keeps angles accurate but distorts sizes and shapes.
• Conic: The map is projected onto a cone and unrolled. This keeps areas accurate near the center but distorts areas further away.
• Azimuthal: The map is projected onto a plane from the globe's center. This keeps distances accurate from the center point out but distorts shapes.
Using Parallels and Meridians
Regardless of the projection used, maps are oriented using latitude and longitude lines:
• Parallels: Circles parallel to the equator, denoted with degrees North (N) or South (S).
• Meridians: Lines of longitude that radiate from the North and South poles, denoted with degrees East (E) or West (W).
In the example, the map projection uses:
• A 32 degree South parallel - designating a latitude of 32 degrees South
• A 25 degree East meridian - designating a longitude of 25 degrees East
So by specifying those two coordinates, the map projection is oriented on the globe. The "BB" indicates southern and eastern orientation.
