Which one can be considered as representing the geographic coordinate system?

1. Altitude
2. Latitude  
3. Attitude
4. None of These

The correct answer is Latitude.

Here’s why:

• Latitude: Latitude, along with longitude, forms the geographic coordinate system. It allows us to pinpoint any location on Earth’s surface.
• Altitude: Refers to height above a reference point, typically sea level. While related to geography, it’s not part of the primary coordinate system.
• Attitude: Refers to a position or orientation, or a state of mind. It has no bearing on geographic coordinates.
• None of these: Since latitude is directly part of the geographic coordinate system, this is incorrect.
