Among the following, the correct statement(s) is (are)

Compounds $$P$$ and $$R$$ upon ozonolysis produce $$Q$$ and $$S,$$ respectively. The molecular formula of $$Q$$ and $$S$$ is $${C_8}{H_8}O.Q$$ undergoes Canninzzaro reaction but not haloform reaction, whereas $$S$$ undergoes haloform reaction but not Cannizzaro reaction


The option(s) with suitable combination of $$P$$ and $$R,$$ respectively, is (are)
