Part A:
Vapour Pressure is the pressure exerted by the vapour which is in thermodynamic equilibrium with its liquid phase or solid phase.
e.g. If I put some water in a glass, after sufficient time some of the water will evaporate and the vapour formed due to evaporation will exert pressure on the water present in the liquid form this is known as the vapour pressure.
None of the above mentioned points are present in the options and hence None of the above is the answer.
Part B :
atmospheric pressure is the pressure due to atmosphere i.e. due to atmospheric weight and it acts on the earth itself.
the second option matches this description well and hence atmospheric pressure is the pressure exerted on the earth by the particles in the air.
Part C :
The boiling point is defined as the temperature at which the vapour pressure of the liquid becomes equal to the atmospheric pressure. Hence the first option is correct
