Solution :-

Right answer is  (d) BaCO3

Thermal stability is directly proportional to the size of the cation i.e., larger the size of the atom, greater is its thermal stability. The biggest cation among the given compounds is Ba.

Thus, BaCO3 will be the most thermal carbonate among the given compounds followed by SrCO3, CaCO3 and MgCO3.
