Given below are two statements : One is labelled as Assertion A and the other is labelled as Reason R :
Assertion A : The density of diamond is much higher than that of ice though both solids adopt analogous structures.
Reason R : The ice lattice is held by hydrogen bonds which are significantly weaker than the covalent C-C bonds in diamond.
In the light of the above statements, choose the correct answer from the option given below:
