Explanation:

Reaction with dilute H2SO4:
- White substance (A) reacts with dilute H2SO4 to produce a colourless gas (B) and a colourless solution (C).

Reaction with acidified K2Cr2O7 solution:
- The reaction between gas (B) and acidified K2Cr2O7 solution produces a green solution and a slightly coloured precipitate (D).

Burning in air:
- Precipitate (D) burns in air to produce a gas (E), which reacts with gas (B) to yield precipitate (D) and a colourless liquid.

Reaction with anhydrous copper sulphate:
- Anhydrous copper sulphate is turned blue on addition of the colourless liquid obtained from the previous step.

Reaction with aqueous NH3 or NaOH:
- Addition of aqueous NH3 or NaOH to solution (C) produces a precipitate which dissolves in the excess of the respective reagent to produce a clear solution in each case.

Precipitate formation:
- The precipitate obtained by addition of aqueous NH3 or NaOH to solution (C) initially is the same, but it dissolves in excess reagent to produce different water soluble complexes in each case.

Therefore, the correct answer is option 'B'.

A colorless aqueous solution contains nitrates of two metals, X and Y. When it was added to an aqueous solution of NaCl, a white precipitate was formed. This precipitate was found to be partly soluble in hot water to give a residue P and a solution Q. The residue P was soluble in aq. NH3 and also in excess sodium thiosulfate. The hot solution Q gave a yellow precipitate with KI. The metals X and Y, respectively, are
