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 cannizzaro reactions but not haloform reaction. Whereas S undergoes haloform reactions but not cannizzaro reactions.
(i) P `overset((i) O_(3)//CH_(2)Cl_(2))underset((ii)Zn//H_(2)O)tounderset((C_(8)H_(8)O))(Q) " " (ii) R overset((i) O_(3)//CH_(2)Cl_(2))underset((ii) Zn//H_2O)tounderset((C_(8)H_(8)O))(S)`
The option (s) with suitable combination of P and R , respectively is (are)
A.
B.
C.
D.
