The reaction in which calcium carbonate produces calcium oxide and carbon dioxide is: CaCO3 = CaO + CO2. Thus, the third option is the right one.
The breaking down of calcium carbonate to calcium oxide and carbon dioxide is called DECOMPOSITION REACTION. A decomposition reaction is a type of reaction in which a single element is broken down into two or more elemental parts, which are less complex than the parent compound.There are three types of decomposition reaction, these are thermal, photo and electrolytic decomposition reactions.

<span>Mitochondria and
chloroplasts are the result of the process called endosymbiosis. Mitochondria
and the chloroplasts are originally from the prokaryotes. They have the ability
to take up inside a large single cell organism which they help each other in
order to produce energy for each other. Endosymbiosis, from the term symbiosis,
the organisms that are symbiotic is living inside the other pair, just like how
the mitochondria and chloroplasts responds to each other.</span>
The answer is B. hope this is helpful
