A sequence of reactions of phosphorus $$\text{P}_4$$ is given below. The correct set of products Q, R, S and T among the following is

$$\text{Q} = \text{PCl}_3$$, $$\text{R} = \text{POCl}_3$$, $$\text{S} = \text{P}_2\text{O}_3$$, $$\text{T} = \text{H}_3\text{PO}_3$$

$$\text{Q} = \text{PCl}_5$$, $$\text{R} = \text{P}_2\text{O}_5$$, $$\text{S} = \text{P}_4\text{O}_6$$, $$\text{T} = \text{H}_3\text{PO}_3$$

$$\text{Q} = \text{PCl}_3$$, $$\text{R} = \text{POCl}_3$$, $$\text{S} = \text{P}_4\text{O}_{10}$$, $$\text{T} = \text{H}_3\text{PO}_4$$

$$\text{Q} = \text{PCl}_5$$, $$\text{R} = \text{P}_4\text{O}_{10}$$, $$\text{S} = \text{P}_4\text{O}_{10}$$, $$\text{T} = \text{H}_3\text{PO}_4$$
