Solution

The correct option is B decomposition reaction
A chemical volcano is an example of a decomposition reaction.
When ammonium dichromate is heated at high temperatures, it decomposes to chromium oxide, nitrogen gas, and steam, so this is called a chemical volcano.
reaction:- $(N H_{4})_{2} C r_{2} O_{7} ⟶ C r_{2} O_{3} + N_{2} + 4 H_{2} O$

The correct option is $B$ .
