In the following table,Column-$I$ shows the structure of a compound,Column-$II$ shows its $IUPAC$ name,and Column-$III$ shows its common name. Match the $IUPAC$ name and common name for each structure given in Column-$I$.
| Column-$I$ (Structure) | Column-$II$ ($IUPAC$ name) | Column-$III$ (Common name) |
| :--- | :--- | :--- |
| $(A)$ $C_6H_4(CHO)_2$ (ortho) | $(i)$ Benzophenone | $(p)$ Acrolein |
| $(B)$ $(CH_3)_2C=CHCOCH_3$ | $(ii)$ Benzene$-1,2-$dicarbaldehyde | $(q)$ Diphenyl ketone |
| $(C)$ $CH_2=CH-CHO$ | $(iii)$ Prop$-2-$enal | $(r)$ Phthaldehyde |
| $(D)$ $(C_6H_5)_2CO$ | $(iv)$ $4-$methylpent$-3-$en$-2-$one | $(s)$ Mesityl oxide |

(A) The correct matches are as follows:
$(A)$ Structure is $o$-phthaldehyde,which is Benzene$-1,2-$dicarbaldehyde $(ii)$ and is commonly known as Phthaldehyde $(r)$. So,$(A-ii-r)$.
$(B)$ Structure is $(CH_3)_2C=CHCOCH_3$,which is $4-$methylpent$-3-$en$-2-$one $(iv)$ and is commonly known as Mesityl oxide $(s)$. So,$(B-iv-s)$.
$(C)$ Structure is $CH_2=CH-CHO$,which is Prop$-2-$enal $(iii)$ and is commonly known as Acrolein $(p)$. So,$(C-iii-p)$.
$(D)$ Structure is $(C_6H_5)_2CO$,which is Diphenylmethanone ($i$ - note: the option list uses Benzophenone as the name,which is the common name,but in this context,it matches the structure) and is commonly known as Diphenyl ketone $(q)$. So,$(D-i-q)$.
