Cuscuta or dodder is a parasitic plant that derives some or all of its nutritional requirements from another living plant. The dodder has no chlorophyll and cannot produce its own food. All parasitic plants have special organs, named haustoria which connect them to the conducting system of their host and provide them with the ability to extract water and nutrient from the hosts. A saprophyte like Monotropa is a plant that does not have chlorophyll and gets its food from dead matter.
So, the correct answer is option B.
