Copper is a metallic mineral.

Option: D  

Explanation:

  • Metallic minerals are the ones that are sources of metals. They are usually abiotic.
  • They are not formed from plant or animal remains.
  • A metal is an element which is hard, lustrous, sonorous, and ductile and has a very high melting point. Copper has all these properties.
  • It has a very ‘high melting point’ at 1085°C. Hence it is a metallic mineral.  
  • Coal, limestone, mica on the other hand are relatively soft, ‘non-lustrous’, non-sonorous and have relatively ‘low melting points’.
  • Hence they are all non-metallic minerals.
