Final answer:
A polymer is a large molecule consisting of many repeating structural units or monomers. The process of formation is called polymerization.
Explanation:
The correct answer to this question is c. polymer. Polymers are large molecules made up of repeating subunits known as monomers. The process in which these monomers connect to form a polymer is called polymerization. An example of a polymer is plastic, which consists of many repeating units of smaller molecules.

Answers
Answer:
D. decomposition
Explanation:
Synthesis reaction occurs when two elements or compounds react to originate a new one:
A + B ⇒ C
Combustion occurs when a fuel reacts with oxygen to form CO₂ and water:
A + O₂ ⇒ CO₂ + H₂O
Replacement reaction can be simple or double. Simple occurs when a simple element replaces others in a compound:
A + BC ⇒ B + AC
Double occurs when two compounds replace elements between them:
AB + CD ⇒ AC + BD
Decomposition reaction occurs when a compound originates two or more compounds
A ⇒ B + C
So, the reaction given is a decomposition chemical reaction.
2MgO → 2Mg + O2 is an example of a decomposition chemical reaction. The answer is letter D. It is not a replacement reaction because no other compound is involved. It is not a combustion reaction because no oxygen is involved.

Limestone is a sedimentary rock. It was formed from small rock or stone particles that have been compacted by pressure. It can be formed either by evaporation or with the help of living organisms.
Calcium carbonate in seawater are used by ocean-dwelling organisms to create their shells and bones; like corals, clams, oysters. When these organism die, their shells and bones are broken down by the waves and settle on the ocean floor where the pressure of the ocean water drives these sediments together to create limestone.
Limestone is created through evaporation. When water containing calcium carbonate evaporates it leaves behind the sediment deposit which in turn becomes limestone after being subjected to the water pressure.
