Answer:

Option (1)

Explanation:

When two or more substances are chemically combined in a fixed proportion of mass, substance formed is a compound.

If Magnesium (Mg) is burned in the presence of Oxygen (O₂), Magnesium oxide (MgO) is formed.

Properties of MgO are different from Mg and O₂ because MgO is a COMPOUND.
