Which among the following oxoacids of chlorine exhibits $+3$ oxidation state of chlorine?

Which of the following halogens does not form oxoacids?

Which of the following processes is used to produce chlorine by the oxidation of $HCl$?

All the compounds listed in Column $I$ react with water. Match the result of the respective reactions with the appropriate options listed in Column $II$.

Column $I$	Column $II$
$(A). (CH_3)_2 SiCl_2$	$(p).$ Hydrogen halide formation
$(B). XeF_4$	$(q).$ Redox reaction
$(C). Cl_2$	$(r).$ Reacts with glass
$(D). VCl_5$	$(s).$ Polymerization
	$(t). O_2$ formation

Given below are two statements: one is labelled as Assertion $(A)$ and the other is labelled as Reason $(R).$
Assertion $(A):$ $ICl$ is more reactive than $I_{2}.$
Reason $(R):$ $I-Cl$ bond is weaker than $I-I$ bond.
In the light of the above statements,choose the most appropriate answer from the options given below:
