dear student,
Decomposition reaction :CaCO3​→CaO+CO2​, in this reaction calcium carbonate is decomposed to calcium oxide and carbon dioxide.
thank you.

It is a decomposition reaction because CaCO3 has decomposed into CaO and CO2.
Hope you are satisfied.

It's a decomposition reaction . Because here one compound is converted into 2 compounds. 
        So your option a is correct

Option(A) is correct. Here CaCO₃ is split to form two new compounds. Which is nothing but Decomposition reaction

 

ADDITIONAL INFO:-

 

COMBINATION REACTION:-

 

When two (or) More elements combine to form a new compound is called a Combination reaction.

 

EXAMPLE :- 2H₂ + O₂ -------> 2H₂O

 

DISPLACEMENT REACTION :-

 

The reaction in which the displacement of the element of high reactivity and the element of low reactivity is called displacement reaction

 

EXAMPLE :- CuSO₄ + Fe ---------> FeSO₄ + Cu
