The correct option is B False
A compound is a substance composed of two or more elements, chemically combined together in a fixed proportion. The properties of a compound are different from those of its constituent elements.
For example, let us consider water (H2O). Water is a compound with hydrogen and oxygen as constituent elements. Oxygen is required for combustion, hydrogen is combustible while water extinguishes fire. Oxygen and hydrogen are gases at room temperature while water is a liquid. Clearly, the properties of water are completely different from those of oxygen and hydrogen.
