Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
yes, latent heat of fusion of ice is $336000 J K g^{- 1}$
Amount of heat absorbed or released during the phase change solid to liquid or liquid to solid respectively is known as latent heat of fusion.
And during phase change temperature remains constant.
