(B) The reaction of the ether $'A'$ $(C_9H_{10}O)$ with conc. $HI$ leads to cleavage.Compound $'A'$ is benzyl vinyl ether $(C_6H_5CH_2-O-CH=CH_2)$.Upon treatment with $HI$,the ether bond cleaves to form benzyl iodide ($C_6H_5CH_2I$,compound $'B'$) and vinyl alcohol ($CH_2=CHOH$,compound $'C'$).Compound $'B'$ $(C_6H_5CH_2I)$ reacts with $AgNO_3$ to give a yellow precipitate of $AgI$.Compound $'C'$ $(CH_2=CHOH)$ is unstable and tautomerizes to acetaldehyde ($CH_3CHO$,compound $'D'$).Acetaldehyde $(CH_3CHO)$ gives a positive iodoform test because it contains the $CH_3CO-$ group.Therefore,the structure of $'A'$ is benzyl vinyl ether.

An organic compound $'A'$ $(C_9H_{10}O)$ when treated with conc. $HI$ undergoes cleavage to yield compounds $'B'$ and $'C'$. $'B'$ gives a yellow precipitate with $AgNO_3$ whereas $'C'$ tautomerizes to $'D'$. $'D'$ gives a positive iodoform test. $'A'$ could be :
