Solution

The correct option is A A- $3$ , B- $4$ , C- $1$ , D- $2$
The correct answer is C
Cascuta sp is a total stem parasite as it attached to the host stem and extract water and all the nutrition from the host plant.
Loranthus sp is a partial stem parasite as it depends up on host only for water and shelter.
Orabranche is a total root parasite because it absorbs all sugars and nutrition and also water from the roots of the host.
Santalum sp a partial root parasite because it only absorbs water and inorganic nutrients from the host root but prepared its own food through photosynthesis.Thats why it is partially depend on host.
