Answer:
Option (3)
Step-by-step explanation:
The Mercator projection is usually defined as the cylindrical map projection that is mainly used for the purpose of navigation while traveling in the vast oceans. The main drawback of using this map projection is that the size of the objects gets distorted as the latitude increases from the equator to the polar regions.
This map projection is very commonly used for navigation purposes as any straight line that is drawn on it remains a line of constant and true bearings. This means that the angles are perfect and it does not show any error, due to which this chart is suitable for navigation in the oceans.
Thus, the correct answer is option (3).
