Answer options

• B. The consequences of potential problem multiplied by the cost of possible legal action.
• C. The impact of an adverse event multiplied by the likelihood of that event occurring.
• D. The likelihood and the probability of a hazard occurring.

Correct answer: C

Explanation

The correct answer, C, accurately defines risk as the impact of an adverse event combined with the likelihood of its occurrence. Options A and B focus on preventive costs and legal consequences, which do not directly measure risk. Option D is vague as it repeats terms without providing a clear calculation of risk.
