Hint: Marble chips are also known as white limestone. They are made up of calcium carbonate. Marble chips are used to add shine to your home as a decorative stone.

Complete step by step answer:
Marble chips are alkaline compounds which when reacted with hydrochloric acid, gives carbon dioxide, calcium chloride and water. Marble chips are made up of calcium carbonate.
Let us see the reaction,
$CaC{{o}_{3}}+HCl\to CaC{{l}_{2}}+{{H}_{2}}O+C{{O}_{2}}$
SO, the correct option is (A) $C{{O}_{2}}$ .

The rate of reaction for the formation of calcium chloride can be changed with the change in size of marble chips.
The smaller size of marble chips gives vigorous reaction. This means that bubbles will appear with a fizzing sound. Smaller chips react faster as compared to large marble chips.
The increase in the concentration of hydrochloric acid when reacts with calcium carbonate, it increases the production of carbon dioxide in reaction, which results in mass loss.


Additional Information:
Marbles are used in street furniture, as a decorative stone, flooring, and buildings. Marble chips consist of a wide range of irregular shaped marble. Marbles are used all around the world to make giant monuments. They are composed of recrystallized carbonate minerals, mainly dolomite.
Calcium carbonates are mostly made up of chalk, limestone.
Physical properties of marble:
Color: They are mostly light-colored rock.
Hardness: Marbles are easy to carve and used for ornamental objects.
Powdered marbles are used as an inert filter in other pills.


Note:
Marble chips are formed from calcium carbonate.
The size of marble chips decides the rate of reaction.
To identify whether the rock is a marble, the acid should produce a fizzy sound on your sample.
Here the hydrochloric acid is the limiting factor.
