In salt analyses, $\mathrm{Cl^-,Br^-}$ and $\mathrm{I^-}$ are identified by adding dilute $\mathrm{HNO_3}$ followed by $\mathrm{AgNO_3}$ solution to the salt solution.
Which of the following statements are correct?

A.	$\mathrm{Cl^-}$ gives pale yellow precipitate.
B.	$\mathrm{Br^-}$ gives pale yellow precipitate which is partially soluble in $\mathrm{NH_4OH.}$
C.	$\mathrm{I^-}$ gives yellow precipitate which is insoluble in $\mathrm{NH_4OH.}$
D.	$\mathrm{Cl^-}$ gives white precipitate which is insoluble in $\mathrm{NH_4OH.}$
E.	$\mathrm{I^-}$ gives purple violet gas.
