• B. Cuscuta
• C. Pitcher plant
• D. (a) and (c) above.

Answer 1

The correct option is B Cuscuta

Nitrogen, phosphorus and potassium are the major nutrients required for plant growth. Some plants such as drosera, venus flytrap and pitcher plant grow in nitrogen deficient soil. Therefore, these plants consume insects to meet their nitrogen requirement.
Cuscuta is a parasitic plant, which obtains food from host plants. Cuscuta obtains food and water by penetrating up to the conducting vessels of host plants.
