The correct answer is B. Sulphur.
A mineral is a naturally occurring, inorganic solid with a definite chemical composition and crystal structure. Minerals are formed through the processes of igneous, metamorphic, and sedimentary rock formation.
Metallic minerals are those that are composed primarily of metals. Metals are elements that are typically shiny, ductile, and malleable. They are also good conductors of heat and electricity. Some examples of metallic minerals include gold, silver, copper, iron, and lead.
Non-metallic minerals are those that are not composed primarily of metals. Non-metals are elements that are typically dull, brittle, and non-malleable. They are also poor conductors of heat and electricity. Some examples of non-metallic minerals include sulfur, carbon, silicon, and oxygen.
In the question, A, B, and C are all metallic minerals. Iron is a metal that is used in a variety of applications, including construction, manufacturing, and transportation. Silver is a metal that is used in jewelry, coins, and electronics. Platinum is a metal that is used in jewelry, catalytic converters, and electronics.
Sulphur is a non-metallic mineral that is used in a variety of applications, including fertilizers, rubber, and gunpowder.
