If an evaluating committee places the burden of proof of the safety of a new chemical on the manufacturer of the chemical, then the committee is using the precautionary principle

Explanation:

This is a method that is used to handle the problems that are related in affecting any person. This principle mainly aims in determining the safety of any new thing before it is released to the public. This will test whether the new thing does not make harm or destroy anything before it is introduced to public.

For instance let us take an example of a medicine introduction. Any new tablets when it is discovered must be tested. Without any testing, releasing it to public will only have adverse effect on them. The given scenario also relates with the precautionary principle since, the safety is considered as an important one by the evaluating committee.  

The answer should be D.)The decay rate does not change
A radioisotope is not stable and will undergo a nuclear decay that will continually decrease its mass. Unlike a chemical reaction, the rate of nuclear decay is not influenced by the temperature of the surface area. So, increases in surface area and decreased temperature will not have any effect.
