• B. Symbiotic, Cuscuta (Amarbel)
• C. Symbiotic, Sundew
• D. Carnivorous, Sundew

Answer 1

The correct option is A

Parasitic,Cuscuta (Amarbel)

Cuscuta derives nutrition from the host plant and is of no benefit to the host. Therefore, it is a parasite. You can also see that the Cuscuta is not green in colour. It does not photosynthesize its food. Also observe how it blocks sunlight of the leaves of its host. This way you can tell that Cuscuta offers no benefit to its host and is a parasite.
