Answer:
b. Pascal
Step-by-step explanation:
Pressure is defined as the ratio between a force and the surface area on which the force is applied:

where F is the force and A is the area.
The force is measured in Newtons (N), while the area is measured in squared meters (
), so the Pascal (Pa), which is the units of measure of the pressure, is defined as:
![[Pa]=([N])/([m^2])](https://img.qammunity.org/2018/formulas/physics/high-school/7widpycxuu4ruv0r8p82ps5kx2ekv1c88u.png)
