  • B
    Increasing intermolecular space$:\ $Solids $<$ liquids $<$ gases
  • C
    Diffusion$:\ $Solid $<$ liquid $<$ gas
  • ✓
    Kinetic energy$:\ $Hydrogen $>$ honey $>$ water
✓

Answer

Correct option: D.
Kinetic energy$:\ $Hydrogen $>$ honey $>$ water
because as we know that kinetic energy of the gases is maximum, liquid is intermediate and solids is minimum. Hence, the order is
Hydrogen $($gas$) >$ honey $($solid but has high density than water$) >$ water.
