Given below are two statements :
Statement (I) : The gas liberated on warming a salt with dil $\displaystyle \mathrm{H}_2 \mathrm{SO}_4$ turns a piece of paper dipped in lead acetate into black, it is a confirmatory test for sulphide ion.
Statement (II) : In statement-I the colour of paper turns black because of formation of lead sulphite. In the light of the above statements, choose the most appropriate answer from the options given below:
