Very true.
It harms our atmosphere, thus effecting climate. Which can kill and sometimes nearly cause organisms to go extinct. It corrupts our air, which is very unhealthy, and can cause lung cancer, and harm our breathing patterns. Which can shorten life expectancy.

The correct option is D. Organisms work best at their optimum temperature and pH, above and below these temperature they will not be able to function as expected. It is possible that the students above use different temperature and pH when they were carrying out their experiments, this will result in different efficiency rate by the yeasts.
