Answer: D
Notes:

A new, curious mineral has been discovered inside a diamond unearthed from a mine in South Africa.  

  • The mineral has been named goldschmidtite, after Victor Moritz Goldschmidt, the Norwegian scientist acknowledged as the founder of modern geochemistry.  
  • Goldschmidtite has an unusual chemical signature for a mineral from Earth’s mantle, according to the University of Alberta, a student of which discovered it.  
  • While the mantle is dominated by elements such as magnesium and iron, goldschmidtite has high concentrations of niobium, potassium and the rare earth elements lanthanum and cerium.  
  • PhD student Nicole Meyer found a single grain of the mineral in the diamond, unearthed in Koffiefontein, South Africa.  
  • The university described it as dark green and opaque.
