Which of the following pairs is mismatched?
a. ehrilich - chemotherapy
b. koch - antibiotics
c. pasteur - proof of biogenesis
d. jenner - vaccination
e. none of the above

The answer is

b. Koch - antibiotics

Explanation:

a)

Paul Ehrlich is considered to be the "father of chemotherapy", so this matching is correct.

b)

The first antibiotic identified was the penincilin, by Alexander Fleming, in 1928, 18 years after Koch had died.

Koch had an important role in combating epidemies, however he did not identify the antiniotics, so this pair is mismatched

c)

This is the production of new living organisms or organelles, proved by Louis Pasteur. So this pair is correctly matched.

d)

Jenner introduced the smallpox vaccine in 1796. So this pair is correctly matched.
