A liquid is transferred from a smaller vessel to a bigger vessel (with bigger surface area) at the same temperature. What will be the effect on vapour pressure?

The correct option is C Remains same
Think about what exactly is changing in case 2 from case 1.
Case 1 ⇒ smaller vessel ⇒smaller volume ⇒ smaller surface area
Case 2 ⇒ Bigger vessel ⇒ Larger volume ⇒ Bigger surface area
Does vapour pressure depend on volume and surface area??
No, it does not.
It depends on the nature of the liquid and temperature, but not on surface area.
Vapor pressure is a measure of pressure of vapour against its liquid/solid counterpart within a closed system. Being pressure, it is measured against a unit area. So it doesn't matter whether the surface area of liquid/solid changes, the pressure per unit area will still be the same.
