We classify each of the reaction as follows:
A. Pb(s) + Hg2SO4 (s) ---> PbSO4(s) +2 Hg(I)
Single replacement reaction
B. NaCI(aq) + AgNO3(aq) --->AgCI(s) +NaNO3(aq)
Double replacement reaction
C. 2H20(I)--->2H2(g) + 02(g)
Decomposition reaction
Hope this answers the question. Have a nice day.

Answer: A is single displacement reaction, B is double displacement reaction and C is decomposition reaction.
Explanation:
Synthesis reaction is defined as the reaction where substances combine in their elemental state to form a single compound.
[tex]A+B\rightarrow AB[/tex]
Decomposition reaction is defined as the reaction where a single substance breaks down into two or more simpler substances.
[tex]AB\rightarrow A+B[/tex]
Single displacement reaction is defined as the reaction where more reactive element displaces a less reactive element from its chemical reaction.
[tex]AB+C\rightarrow CB+A[/tex]
Element C is more reactive than element A.
Double displacement reaction is defined as the reaction where exchange of ions takes place.
[tex]AB+CD\rightarrow AD+CB[/tex]
Combustion reaction is defined as the reaction where a hydrocarbon reacts with oxygen gas to produce carbon dioxide and water molecule.
[tex]\text{hydrocarbon}+O_2\rightarrow CO_2+H_2O[/tex]
For the given options:
Option A:
[tex]Pb(s)+Hg_2SO_4(s)\rightarrow PbSO_4(s)+2Hg(l)[/tex]
This is considered as a single displacement reaction because lead is more reactive than mercury.
Option B:
[tex]NaCl(aq.)+ AgNO_3(aq.)\rightarrow AgCl(s)+NaNO_3(aq.)[/tex]
This is considered as a double displacement reaction.
Option C:
[tex]2H2O(l)\rightarrow 2H_2(g)+O_2(g)[/tex]
This is considered as a decomposition reaction.
Hence, A is single displacement reaction, B is double displacement reaction and C is decomposition reaction.
