Text Solution

Verified by Experts

The correct Answer is:
C
In gallium, the crystal structure is different, suggesting that Ga consists of almost discrete `Ga_(2)` molecule, that's why its melting point is lowest. Ga exists as liquid from `30^(@)C` upto `2000^(@)C` and hence, it is used in high temperature thermometry.
