She feel warm due to sun shining on her back which shows the transfer of energy due to Radiation Mode of heat transfer.

Because in this case we do not need any medium to transfer the heat and all energy is transferred due to electromagnetic waves.

She feels warm sand under her feet which shows the heat transfer due to conduction mode.

Because in this mode of heat transfer the heat is transmitted by direct contact.

A cool breeze is blowing from the water which shows the heat transfer due to convection mode.

Here thermal energy is being transferred by the moving medium molecules.
