B

`Na`

C

`K`

D

`Rb`

Text Solution

Verified by Experts

The correct Answer is:
A
`Li` has highest melting point among alkali metals. All alkali metals have low M.P. The M.P. decrease down the group. The low M.P. are attributed to their larger atomic size due to which the binding energies of their atoms in the crystal lattice are low.
