Incorrect Statement: (I) Oxygen is highly combustible and hydrogen is a supporter of combustion.

Explanation:
Combustibility refers to the ability of a substance to burn or ignite. In the given options, statement (I) is incorrect because it states that oxygen is highly combustible, which is not true. Let's analyze the properties of oxygen and hydrogen to understand why statement (I) is incorrect.

Properties of Oxygen:
- Oxygen is a gas that supports combustion.
- It is not itself combustible or flammable.
- Oxygen is essential for combustion to occur, as it helps in the process of oxidation.
- It acts as an oxidizing agent, enabling other substances to burn.

Properties of Hydrogen:
- Hydrogen is a highly flammable gas.
- It is combustible and burns easily in the presence of an oxidizing agent like oxygen.
- Hydrogen is not considered a supporter of combustion.

Based on the properties mentioned above, we can conclude that statement (I) is incorrect. Oxygen is not highly combustible, but rather it supports combustion by acting as an oxidizing agent. Hydrogen, on the other hand, is highly combustible and burns easily when combined with oxygen.

Overall, the correct statements about oxygen and hydrogen are:
- Oxygen is a supporter of combustion.
- Hydrogen is highly combustible.

Therefore, the incorrect statement is (I) Oxygen is highly combustible and hydrogen is a supporter of combustion.
