An alkene $(X)$ on ozonolysis gives propanal and ethanal. What is $X$?

Consider the following sequence of reactions: $CH_3-CH=CH_2$ $\xrightarrow[700\,K]{Cl_2} A$ $\xrightarrow[420\,K, 12\,atm]{Na_2CO_3} B$ $\xrightarrow[(ii) NaOH]{(i) HOCl} C$. Compound $C$ is:

Which compound would give $5-$keto$-2-$methylhexanal upon ozonolysis?

The product $(P)$ is:

$A$ benzene derivative did not produce a white precipitate with ammoniacal silver nitrate solution (Tollens' reagent) but decolorized cold dilute alkaline $KMnO_4$ solution (Baeyer's reagent). The compound is:
