Q. Which one of the following sets of items in the options given below are correctly categorised with one exception in it?
A) Items: UAA, UAG, UGA; Category: Stop codons; Exception: UAG
B) Items: Kangaroo, Koala, Wombat; Category: Australian marsupials; Exception: Wombat
C) Items: Plasmodium, Cuscuta, Trypanosoma; Category: Protozoan parasites; Exception: Cuscuta
D) Items: Typhoid, Pneumonia, Diphtheria; Category: Bacterial diseases; Exception: Diphtheria
Explanation
[Solution from source] Plasmodium and Trypanosoma are protozoan parasites, while Cuscuta is a parasitic flowering plant, so it is the true exception. UAG is itself a stop codon, the wombat is a marsupial, and diphtheria is a bacterial disease, so the 'exceptions' in the other sets are not exceptions. Answer (3).
