---|---|---|---
1| UAA, UAG, UGA| Stop codons| UAG
2| Kangaroo, Koala, wombat| Australian, marsupials| Wombat
3| Plasmodium, Cuscuta, Trypanosoma| Protozoan| Cuscuta
4| Typhoid, pneumonia, diphtheria| Bacteria disease| Diphtheria

(A) 1
(B) 2
(C) 3
(D) 4

Answer 1

See the items given in the table and compare the various properties and the nature of them to know the category and the exception. If two items have the same category with the only one exception, then it is the answer.

Complete answer:

Plasmodium and Trypanosoma are protozoans. Protozoans are the organisms that belong to the kingdom protista. They are divided into different types based on their locomotory organelles.
Plasmodium:Plasmodium is the protozoa which is of sporozoan origin. They are endoparasites. They don’t possess Locomotory organelles in them. It is the malarial parasite and it causes malaria in human beings by using the vector mosquito. It needs one host organism to complete its life cycle. For example, female Anopheles mosquito and the human beings as the host.
Trypanosome: Trypanosoma is a zooflagellate. They have flagella for movement from one place to the other. In humans, these parasites live in the blood plasma and cause sleeping sickness.
Cuscuta:Cuscuta is a parasitic plant. Unlike the other two it belongs to the plant kingdom. It is an angiosperm. It has no chlorophyll, so it can't perform photosynthesis. Since it cannot prepare its own food, they develop on other plants taking their supplements of nutrients from that and make that plant weak.
Hence all the other options do not meet the condition, but this option has two correctly categorized one with the one exception.

Thus, the correct answer is option (C) .

Note: This cuscuta plant has no roots and no leaves for the photosynthesis. They only possess the stem regions. Hence, they are known as stem parasites and this stem absorbs the vitamins and the minerals from the nearby photosynthetic plants.
