Solution

The correct option is A $100 N m^{- 2}$
$1$ bar is nearly equal to the atmospheric pressure i.e., $10^{5} N m^{- 2}$ .
So, $1$ millibar $= 10^{- 3}$ bar
As, $1$ bar $= 10^{5} N m^{- 2}$
Thus $10^{- 3}$ bar $= 10^{2} N m^{- 2}$
So, $1$ m bar is equal to $10^{2} N m^{- 2}$
Option A is correct.
