Assertion (A) : Alkali metals are soft and have low melting and boiling points. Reason (R) : This is because interatomic bonds are weak.
- A Both (A) and (R) are not true
- B (A) is true but (R) is not the correct explanation of (A)
- C (A) is true but (R) is false
- D Both (A) and (R) are true and (R) is the correct explanation of (A)
