  • There are two types of carotenoids: Carotenes and Xanthophylls.
  • The difference between the two groups is chemical: xanthophylls(C_{40}H_{56}O_{2}) contain oxygen, while carotenes (C_{40}H_{56}) are hydrocarbons and do not contain oxygen. 
  • Also, the two absorb different wavelengths of light during a plant’s photosynthesis process, so xanthophylls are more yellow while carotenes are orange. 
  • The common type of carotene is beta-carotene.
  • The common type of xanthophyll is lutein.
  • The ratio of xanthophyll to carotene in plants is 3:1 or 2:1.

The common type of xanthophyll is lutein. Hence, the correct answer is option b.
