A. N₂O₄ on hydrolysis produces HNO₃ and HNO₂.

N₂O₄ + H₂O $\to$ HNO₃ + HNO₂

B. Hydrolysis of XeF₂ is a redox reaction.

2XeF₂(s) + 2H₂O(l) $\to$ 2Xe(g) + 4HF(aq) + O₂(g)

In this reaction, Xe is reduced (from +2 to 0) and O is oxidized (from -2 to 0). So, this statement is CORRECT.

C. Partial hydrolysis of PCl₅ produces POCl₃ and HCl.

PCl₅ + H₂O $\to$ POCl₃ + 2HCl

One mole of PCl₅ produces two moles of HCl on partial hydrolysis.

D. NCl₃ on hydrolysis produces NH₃ and HOCl.

NCl₃ + 3H₂O $\to$ NH₃ + 3HOCl

It produces hypochlorous acid (HOCl), not hydra acid.

The final answer is $\boxed{B}$
