The water at the top receives sun rays and the specific heat capacity of water is high so it gets heated up and hence heat is not distributed instantly to the lower layers of the lake.

You have asked incorrect question.
But I guess you mean to ask that why water at top is warmer than the that of bottom. It happens because it receives direct rays of sun or due to warm temperature which makes the surface of water warm. When it received sun rays, convection takes place which first makes water molecules of top warm and then reach to bottom. Thus, water at top is warmer.

Water is warmer at the bottom of a lake than at the top because the gravitational potential energy is converted first to kinetic energy of the falling water, and finally to heat energy as it comes to rest at the bottom.
This one is correct

Sorry for answering wrong earlier
Sorry that was also wrong
It happens due to convection.water molecules receives heat and goes down as warm molecules are more heavier. Thus, cooler molecules rises up and that's what the reason is that water molecules at bottom are warmer.
This one is 200% correct
