Answer:

quartz (SiO2)n

Explanation:

Melting point is defined as the temperature or point at which the substances change its state from solid to liquid.

Quartz (SiO2)n has high melting point than O2 because Quartz (SiO2)n is found in the form of hard, crystalline mineral that is made up of silicon and oxygen atoms having strong covalent bonds between all the atoms. So, a lot of energy is required to break the bond between the atoms and it has a high melting point.

Hence, the correct answer is quartz (SiO2)n.
