D. Risk

RISK can be seen as a tendency or likelihood that a person or an individual may encounter, faced or be exposed to something that may be harmful or have an adverse health effect on such person Example a house that has a foundation that is not strong is an hazard reason been that their is likelihood or tendency that a person or an individual might be harmed if the house collapsed because the foundation of the building is not strong for the building to stand long on it without collapsing.
The statements which are true about half-life are given below:
- A radioactive element's half-life stays the same when its temperature changes.
- A radioactive element's half-life stays the same when the pressure upon it changes.
Thus, the correct options are B and F.
<h3>What is Half-life?</h3>
The half-life of any radioactive element may be defined as the time taken for the radioactivity of a specified isotope to drop to half of its original value.
The above statement is true about the half-life of any radioactive element because the half-life of any substance does not depend on pressure, temperature, and concentration.
Therefore, it is well described above.
