Let's go through the options:

A. Solar energy: Solar energy is a type of renewable energy that comes from the sun. It is harnessed using technologies like solar panels and is considered a natural resource.

B. Diamonds: Diamonds are minerals that are formed deep within the Earth's crust. They are extracted and used for various purposes, such as jewelry and industrial applications. Therefore, diamonds are a natural resource.

C. Iron: Iron is a type of metal that is obtained from iron ore through mining and is used widely in construction, manufacturing, and other industries. Iron is indeed a natural resource.

D. Wood: Wood is a material that comes from trees, which are a part of the biological resources category. It is utilized for building, furniture making, paper production, and numerous other applications. So, wood is also a natural resource.

Therefore, based on our analysis, none of the options listed (A. Solar energy, B. Diamonds, C. Iron, and D. Wood) is NOT a natural resource. All of them qualify as natural resources.
