The correct answer is C. Tissue
Explanation:
In the diagram, x is between organ and cell level. This implies this level of organization is smaller than an organ but no as small as one cell. In this context, the most suitable term to add to this level is a tissue because these are structures composed of specialized cells, which shows this level encloses cells. Also, a group of tissues forms an organ; this implies the organ is the level that follows the tissue. Examples of this include muscle tissue composed of muscle cells and that is part of organs including the heart.

Answer: C. The environment changed suddenly from a shallow ocean setting to a river system.
Explanation:
The presence of the fossils of shallow oceanic creatures like corals points to the fact that the environment was a shallow ocean at some point. There is also a presence of a layer on top of that which points to a river system.
The fact that the oceanic fossils are beneath the river system layer means that the ocean came first and the river system layer came second. The environment must therefore have been a shallow ocean setting that changed into a river system.
The answer is either a or c
