Correct Answer: Cuscuta

Solution : The correct option is Cuscuta .

Dodder seedlings make contact with a host plant and then put forth haustoria, which are specialised structures that enter the host plant's tissues. Dodder uses the haustoria to suck water and nutrients from the host plant, thus parasitizing it. Dodder can be harmful to the growth of the host plant and can influence crop plants, making it an agricultural pest in some areas.
