The definition of 1 atm is the pressure exerted by a column of mercury 760 mm (or 76 cm) in height, hence 1 atm is equal to 760 mm Hg. Torr is an alternative unit for mm Hg, hence option C is also correct. However, option A is incorrect as 1 atm is not equal to 760 cm Hg and option D is incorrect as it is the same as option B.
