The correct answer is - A. coal.
The coal is classified as organic sedimentary rock because the basis for its formation is the organic matter. It is a rock that is formed on the basis of dead organic matter from the Carboniferous, mostly of trees that existed in this period. Over a long period of time, tens and hundreds millions of years, the coal, under all the temperature and pressure that had influenced it started to take the shape in which we now know it. It can be mixed with other material, but in general comes in the non-mixed organic based form.

Answer:
Abstract. DNA polymerase I (pol I) processes RNA primers during lagging-strand synthesis and fills small gaps during DNA repair reactions. However, it is unclear how pol I and pol III work together during replication and repair or how extensive pol I processing of Okazaki fragments is in vivo
Explanation:
<span>Carbon is the answer you are looking for. However, not all carbon containing molecules are organic. Examples being carbon oxides such as CO (carbon monoxide) and CO2 (carbon dioxide). Some Chemists classify organic compounds as having a C-H bond present but this is not completely correct as this excludes molecules like benzenehexol (benzene with an alcohol group on each carbon rather than a hydrogen) which are considered organic. A solid definition of an organic molecule is not certainly agreed. Just remember that: all organic molecules contain carbon but not all carbon containing molecules are organic.</span>
