Answer:
The vapour pressure z essentially d the force experienced by any container due to the collision of the vapours of a substance in d container.....
solids usually dont exhibit any vapour pressure.....however there are exceptions...eg: naphtahalene (a sublime compound)
now, its obvious that more amt of vapours, higher d vapour pressure......n we also know, that warm water produces more vapours than cold water (due to easy evaporation).....
Thus this explains why warm lakes have higher vapour pressure
Optn B is d ans
