Well there alot of challenges faced by biologist researchers during the research of infectious disease, however major of those include the followings:1- Defining and measuring the fitness for pathogens across the scales2- Developing models to capture the impact of co-infection on the evolutionary process3- Modeling how pathogen characteristics shape the evolution of hose immune diversity4- Understanding the maintenance of pathogen diversity5- Developing the better models for the impact of genetic systems on pathogen evolution .
Hope this helps!

Answer:
Option (B) Ethylene gas is a chemical signal through which ripening fruits trigger the ripening process in other fruits.
Explanation:
The ethylene hormone triggers the ripening process of fruit. However, in order to slow down the ripening process the action of ethylene is to be blocked. All fruits are capable to produce ethylene up to a certain level after which they start ripening. There are some classes of fruits that respond to the external ethylene such as apple, mango, tomato etc.
Hence, option B is correct
B) The evidence did not support the idea
