The set with correct order of acidity is
(a) \(\mathrm{HClO}<\mathrm{HClO}_{2}<\mathrm{HClO}_{3}<\mathrm{HClO}_{4}\)
(b) \(\mathrm{HClO}_{4}<\mathrm{HClO}_{3}<\mathrm{HClO}_{2}<\mathrm{HClO}\)
(c) \(\mathrm{HClO}<\mathrm{HClO}_{4}<\mathrm{HClO}_{3}<\mathrm{HClO}_{2}\)
(d) \(\mathrm{HClO}_{4}<\mathrm{HClO}_{2}<\mathrm{HClO}_{3}<\mathrm{HClO}\)
