The Correct Option is B

Solution and Explanation

Amanita muscaria is a member of class Basidiomycetes. It is a poisonous mushroom and has hallucinogenic properties. It produces a toxic alkaloid, muscarine, which mimics the effects of acetylcholine and binds to muscarinic receptors as well as ibotenic acid which also binds to different receptors. This leads to excitation of neurons bearing these receptors and hence hallucinations.

Biological Classification

The process of grouping living organisms into categories is called biological classification. The most modern 5-kingdom classification was put ahead by an eminent scientist R.H.Whittaker. The five-kingdom classification is based on the criteria like cell structure, mode of nutrition, body form, and reproduction. One of the most important characteristics of this system is that it follows the evolutionary sequence of living organisms. The organisms are classified into distinct taxa or levels like Kingdom, Phylum, Division, Class, Order, Family, Genus, and Species. The 5 kingdoms are as follows:
