In Column-$I$ formula,in Column-$II$ general name and in Column-$III$ $IUPAC$ name are given. Match the items in Column-$I$ with the appropriate items in Column-$II$ and Column-$III$.

Column-$I$ (Formula)	Column-$II$ (General Name) and Column-$III$ ($IUPAC$ Name)
$(A)$ $HCOOH$	$(i)$ Succinic acid,$(x)$ Methanoic acid
$(B)$ $CH_3CH_2CH_2COOH$	$(ii)$ Oxalic acid,$(y)$ Ethanedioic acid
$(C)$ $(COOH)_2$	$(iii)$ Formic acid,$(m)$ Butanedioic acid
$(D)$ $(CH_2)_2(COOH)_2$	$(iv)$ Butyric acid,$(n)$ Butanoic acid

Assertion : $RCOCl$,$(RCO)_2O$ and $RCOOR'$ all react with Grignard reagents to form $3^o$ alcohols.
Reason : $RCOCl$ reacts with $R_2Cd$ to form ketones but $(RCO)_2O$ and $RCOOR'$ do not react at all.
