Answer: Option (B) is the correct answer.
Explanation:
As it is given that the melting temperature of substance is 1200 degree Celsius and its density is 16.7 [tex]g/cm^{3}[/tex].
Since, the temperature is very high and no solution or molecule exists at such a high temperature.
Whereas a compound is defined as the substance which contains two or more different elements which chemically combine together in a fixed ratio by mass.
Compounds in the form of alloys have high melting temperature.
Thus, we can conclude that the given unknown substance is most likely a compound.
