Correct option is (d) 2276

To explain I would say: Low melting point of gallium is due to the fact that it consists of Ga2 molecules and gallium remains liquid up to 2276 k. Hence it is used in high-temperature thermometer. Gallium as a chemical symbol that is Ga and its atomic number is given as 31.
