Question

Select the odd one out on the basis of the disease causing agent ?​

Answer 1

Answer:

The given question is supposed to be a multiple choice question with four options.

In this Multiple Choice Question, the options are,

(A) Cholera  

(B) Measles

(C) Whooping cough

(D) Tuberculosis

Out of these options the correct one is option C which indicated that whooping cough is much different than cholera, measles and tuberculosis. Whooping cough happens because of some form of infection. It is a bacterial infection which is contagious in nature. It can be avoided by the help of a vaccine.   But the others are different in nature.

Answer 2

Measles is the ‘odd one out’ on the basis of the ‘disease causing agent’.

EXPLANATION:

Measles is caused by the Measles virus. A virus is a microscopic organism that cannot survive without a living host. Whooping Cough is caused by a bacterium called Bordetella pertussis. ‘Cholera’ is caused by Vibrio cholerae. Tuberculosis is caused by Mycobacterium tuberculosis.  

The last three diseases are caused by bacteria. A bacteria is a ‘microscopic organism’ that can be effectively destroyed by antibiotics unlike a virus which does not react to antibiotics. Measles is the odd one out as it is caused by a virus and not bacteria.
