C. boric acid
D. `0.3 "ppm"` aqueous solution of `Cl_(2)`

Answer

B, C

Explanation

Antiseptics are the chemical substances which either kill or prevent the growth of microorganisms.
(a) `CHCl_(3)` (chloroform) was used as an anaesthesia in surgery but not its is used in the production of the freon refrigerant `R-22`.
(b) lodoform `(CHI)_(3)` produces iodine on coming in contact with skin, so it is used as an antiseptic for wounds.
(c ) Boric acid `(H_(2)BO_(3))` in dilute aqueous solution is a weak antiseptic for eyes. Thus, chemical messenger gives messagle to the all without entereing the cell.
(d) Chloric in the concentration of `0.2`, to `0.4 "ppm"` in aqueous solution and sulphur dioxide in very low concentrations, are disinfectants.
