Question

what is a rock?

naturally occurring solid mass of minerals, or a collection of minerals
high temperatures and pressure act on a fossil
naturally occurring, inorganic solids with a definite chemical composition
elements essential for health that the body needs to develop and function normally

Explanation:

A rock is defined as a naturally occurring solid mass made up of minerals or a collection of minerals. The second option describes the formation of metamorphic rocks from fossils (incorrect as fossils are not the main starting material for most rocks in a general rock - definition context). The third option describes minerals (not rocks). The fourth option describes nutrients for the body.

Answer:

naturally occurring solid mass of minerals, or a collection of minerals
