Answer
A is True and R is False.
Reason — Both antiseptics and disinfectants are used to kill or inhibit the growth of pathogenic microorganisms that can cause disease.
Antiseptics are used on living tissues (like skin) to kill or inhibit microbes e.g. Dettol, iodine. Disinfectants are used on non-living surfaces (floors, instruments) and not inside the human body, as they can be too harsh or toxic.
