Quizplus · Accepted Answer

According to the factor table provided, the correction factor for a temperature of 17°C is -2.2 mm Hg. 
Therefore, the corrected pressure can be calculated as: 
Corrected pressure = Mercury barometric reading + Correction factor 
= 760 mm Hg - 2.2 mm Hg 
= 757.8 mm Hg 
Hence, the correct answer is option C.
