dii) I am not too sure for this one. But i would say no.
Because of the presence of chloride, chlorine gas is liberated.

E) No because Cl is present in acid chlorides but not in alkane.Combustion of Cl products is expected(because we don’t really know what will be liberated) when we combust acid chlorides

Well Done. Answers are almost all correct. =)
For Dii), Answer is NO.
But the products that will be formed is not Cl2 gas, just to clarify.
Experimentall, it has been proven to release Hydrogen Chloride (HCl) gas & Phosgene (CCl2O) gas. But no worry, it is not covered in GCE O Level. You just need to know that products of combustion will formed some new compounds that contain Cl inside.
