Beaker (I) - Common salt Beaker (II) - Alum Beaker (III) - Potassium nitrate Beaker (IV)- A few drops of barium chloride and a few drops of dilute `H_2 SO_4`. After sometime, the contents of the beakers were filtered. The contents of which beaker will leave residue on the filter paper?

A

Beaker (I)

B

Beaker (II)

C

Beaker (III)

D

Beaker (IV)
