Solution

The correct options are
A pascal (Pa)
B newton per $m^{2}$
The pressure is the force per unit area. So, $P = F / A$
The unit of force is newton (N) and unit of area is $m^{2}$ .
Thus, the unit of pressure is $N / m^{2}$ .
Pascal is the SI unit of pressure. It is equal to one newton divided by one square meter.
