@All.

Carbon dioxide won't be found in Soda water in the free state, what most candidates from non-science background see is the Carbonated part and not the actual chemistry, even then it is known as CARBON 'ated' and not carbon dioxide drink

Carbon dioxide dissolves with water under high pressure to form H2CO3 -carbonic acid, and when pressure is removed dissolved CO2 escapes in the form of effervescence
H2O(l) + CO2(g) -> H2CO3(aq).

It also imparts the tingly fizz attribute of soda water or else can anybody get that tingly feeling tasting Co2 and H2O separately.

Carbonated water or Soda water is water that has been infused with Carbon dioxide gas under pressure. This produces a bubbly drink that's also known as sparkling water, club soda, soda water, seltzer water and fizzy water. With the exception of seltzer water, they usually have salt added to improve the taste.

The gasogene (or gazogene, or seltzogene) is a late Victorian device for producing carbonated water. It consists of two linked glass globes: the lower contained water or other drink to be made sparkling, the upper a mixture of tartaric acid and sodium bicarbonate that reacts to produce carbon dioxide.

The answer is Carbonic acid which is formed as a result of carbon dioxide mixing with water at High Pressure.

Carbon dioxide is infused into the water under very high pressure and when it dissolves in water it forms a very weak acid known as carbonic acid.

It is a type of carbonated beverages-carbonated beverages contain carbon dioxide. We see while drinking soda our tongue gets something different because of carbon dioxide mixed in it.

Soda water = carbonic acid (H2CO3).

Then it should not be in choice it is to confuse the student.

Carbon dioxide after dissolving in water becomes carbonic acid. Hence, CO2 is present as H2CO3.

Yeah as all are saying it must be carbonic acid: Co2+ H2o = H2CO3. So it is carbonic acid.

Carbonic acid is not stable due to hydrogen bonding so readily converted to CO2 + H2O.

Carbonic acid breaks as water and carbon dioxide, so carbon di oxide is right answer.
