Answer: The correct answer is - B. heterotrophic, chitin in cell walls.
Fungi is an kingdom of eukaryotic, heterotrophic organisms (like animals, as they obtain food from other organisms) that obtain their food by absorbing nutrients from environment (either from living or from non living organic matter).
This is because they do not have chlorophyll pigment (unlike plants, which are autotrophic organisms) to syntheisize their own food.
They are non vascular organisms (as no vascular tissues are present in them such as xylem and phloem) unlike plants.
Cell wall of fungi is primarily made up of chitin (unlike plants, which contain cellulose in their cell wall).
Thus, option B) is the right answer.
