Answer: The correct answer is geographical map.

Explanation:

Model is defined as the three dimensional representation of a proposed structure in a smaller scale.

For the given options:

Option 1: PV = nRT

This is a proposed law. This law is known as ideal gas law. A law is defined as the rule which defined a correct procedure. For any gas behaving ideally, this law is used.

Option 2: Geographical map

Map is defined as the diagrammatic representation of an area of land or sea which also shows physical features, roads, cities etc..

A 3-D model can be prepared for geographical map.

Option 3: I believe that aliens exist

This is a hypothetical statement. It is a smart guess by the means of set of assumptions and observations. For its validation, we need to conduct some experiments.

Hence, the correct answer is geographical map.
