Solution

The correct option is B

Only statement 1 is correct


Here, only statement 1 is correct and statement 2 is completely out of context.

The air exerts pressure on liquids and solids surfaces due to its weight. So, the force applied by the air column present above us is called atmospheric pressure. At sea level, atmospheric pressure is about 100 kPa (Pa is the unit of pressure) which is equivalent to the weight of ten cars pressing on us every square meter(statement 1). But we aren't crushed by this huge pressure because it is matched by the pressure of the human body (your lungs and blood system).
