The answer is (B): The sea level pressure value for this airport will be "less than" 1027 mb.
Explanation:
The pressure decreases with increasing altitude.
As the observation was taken at 182 ft below sea level, the pressure at sea level would be less than 1027 Mb, understanding that the pressure level in the atmosphere may be interpreted as the total weight of the air above a unit area at any elevation. At higher elevations, there are fewer air molecules above a given surface than a similar surface at lower levels.
