    option (c) 14.7 lbs

    Explanation:

    Data provided in the question:

    Area of the column = 1 square inch

    Now,

    we know Air pressure at the ground surface level from the atmosphere

    = 14.7 Psi

    also, it can be represented as

    14.7 Psi = 14.7 pounds per square inch

    Therefore,

    Weight of the air weigh within a column that is 1 square inch in area

    = Air pressure * Area

    = 14.7 pounds per square inch * 1 square inch

    = 14.7 pounds i. e 14.7 lbs

    Hence,

    The answer is option (c) 14.7 lbs
