(a) Sulphurous acid is a reducing agent because sulphur readily gets oxidized itself to more stable +6 state.

(b) Fluorine forms only one oxoacid Because of absence of d-orbital in Fluorine.

(c) Boiling point of noble gases increases from He to Rn because size increases from Helium to Radon and hence, dispersion or van der Waal forces increase from Helium to Radon.
