Answer:

Weight of air per unit area is pressure due to atmosphere. So here correct answer is Weight

Step-by-step explanation:

As we know that air pressure is given by

P = (Force)/(Area)

now we know that force here due to air is due to the weight of the air

so here in order to calculate the weight we will have

Weight = mg

$Weight = \rho Ah g$

here we know that

Ah = volume of air above the point where pressure is to be calculated

now from above formula we have

$P = (\rho AH g)/(A) = \rho g h$

so here we can say that pressure is due to weight of air
