Which of the following compounds is obtained when anisole is heated with dilute sulfuric acid?

The products formed when diethyl ether is reacted with cold $HI$ are

Assertion : Iodide ion combines with smaller group to avoid steric hindrance.
Reason : With $HI$,anisole gives iodobenzene and methyl alcohol.

When ether is reacted with $O_2$,it undergoes explosion due to the formation of:

$A$ mixed ether $(P)$, when heated with excess of hot concentrated hydrogen iodide, produces two different alkyl iodides which when treated with aqueous $NaOH$ give compounds $(Q)$ and $(R)$. Both $(Q)$ and $(R)$ give a yellow precipitate with $NaOI$. Identify the mixed ether $(P)$:

The reaction of methyl chloride with silver acetate yields $................$.
