Match the entries of column I with appropriate entries of coloumn II. Each entry in column I may have one or more than one correct option from column II. If the correct matches are A-p, s , B-r, C-p, q , D-s, then the correctly bubbled 4 `xx` 4 matrix should be as follows :
`{:(,"Column I",,"Column II"),((A),H_(3)PO_(3) overset(Delta)rarr,(p),"One of the products acts as a reducing agent."),((B),PCl_(3) + H_(2)O overset(Delta)rarr,(q),"One of the products is a tribasic non-reducing acid."),((C),NO_(2) + H_(2)O rarr,(r),"Dehydration"),((D),HNO_(3) + P_(4)O_(10) overset(Delta)rarr,(s),"In one of the products, central atom has +5 oxidation state."):}`

Answer

`A-p,q,s;C-p,s;D-r,x`
