B
Ectoparasitism
C
Brood parasitism
D
Predation
Detailed Solution
$Cuscuta$ (dodder) is a parasitic plant commonly found growing on hedge plants.
It has lost its chlorophyll and leaves during evolution and derives its nutrition from the host plant through haustoria.
It lives on the external surface of the host, twining around its stem, so it is an ectoparasite.
Endoparasites live inside the host body (e.g., tapeworm, liver fluke); brood parasitism is shown by birds such as the cuckoo laying eggs in the nest of the crow; predation involves killing and eating the prey.
Hence $Cuscuta$ is an example of ectoparasitism.
