A. Items- Kangaroo, koala, wombat
Category- Australian marsupials
Exception- Wombat
B. Items- Plasmodium, Cuscuta, Trypanosoma
Category- Protozoan parasites
Exception- Cuscuta
C. Items- Typhoid, pneumonia, diphtheria
Category- Bacterial diseases
Exception- Diphtheria
D. Items- UAA, UAG, UGA
Category- Stop codon
Exception- UAG

Answer 1

Hint: A certain group of items is given that belong to the same category may it be the type of the organisms, a genetic codon, type of diseases or animals, and out of which one of the items may be an exception to the given category.

Complete step by step answer: Option A) Many marsupials are found in Australia and marsupials are the creatures that give birth to their baby in an underdeveloped stage and then the baby grows in the mother’s pouch and kangaroo, koala, and wombat are the Australian marsupials.
Option B) Protozoan parasites are the protozoans that live in a host cell and Plasmodium, and Trypanosoma are protozoan parasites but Cuscuta is a plant, mainly an angiosperm parasite as it is an angiospermous plant that takes up the nutrients for its own need from the neighboring plants and thus the word angiosperm parasite.
Option C) Bacterial diseases are the diseases that occur due to the bacterial species that invade the host human cell and disrupt the metabolism of the human leading to diseased condition and typhoid, pneumonia, and diphtheria are caused by different bacterial species like typhoid is caused by Salmonella typhi, pneumonia is caused by Streptococcus pneumonia, and diphtheria is caused by Corynebacterium diphtheriae.
Option D) Stop codons are the genetic codons that allow the termination of the translation process and UAA, UAG, and UGA are the three stop codons.
Hence, the correct answer is option (B).

Note: Cuscuta being an angiosperm parasite gets its water, nutrients, and macromolecules from the surrounding plants and is commonly known as scaldweed, beggarweed, lady's laces, fireweed, etc.
