Explanation:
C. ferns.
Explanation:
The ferns are ancient plants that have managed to survive until the present. They are not closely related to the dominant plants nowadays, the flowering plants, but instead they are closely related with plants that have gone extinct tens and hundreds of millions years ago. Even though the ferns are not the dominant plants, they have managed to find a niche and firmly hold onto it, so they remained widespread, normally occupying the lower layers of the forests.
Unlike the flowering plants that produce flowers and then seeds in order to reproduce, that is not the case with the ferns. The ferns actually reproduce through spores, being widely dispersed by the wind and managing to spread out and reproduce over relatively large territory very quickly.
The correct solution for this is explained the first option. Since water has an equivalent amount or number of H ions and OH ions, pure water itself is not slightly acidic nor basic. This equality of ions, causes the pH of water to be around the mid point of the pH scale which goes from 0 - 14, and thus is 7. This is a neutral pH.

<span>The hypocenter, or focus is the point where the earthquake really starts. It's located under the surface in the tectonic plate boundary. </span><span> <span> <span> </span> </span> </span>
The epicenter is the point on the surface of the earth that's directly above the hypocenter.
