b. New Orleans, LA (2 m below sea level)

Explanation:

Atmospheric pressure is due to the weight of the air above the region: the higher the region the less the amount of air above it, so the lower the atmospheric pressure. The lower the region the more the amount of air above it, so the higher the pressure.

The normal atmospheric pressure at sea level is 1 atm which is equal to 760mmHg. Thus, you must find which region among the given options represents an altitute lower than sea level. That is New Orleans, LA, because it is 2m below sea level.
