Due to a lack of adherence to the risk response plan, there are numerous safety concerns within the scope of a building project. Which of the following MOST likely explains this issue?

Risks were clearly identified - the existence of a risk response plan proves identification had already occurred; the problem is not a failure to find the risks.

Mitigation is the risk response strategy that involves taking proactive actions to reduce the probability or impact of a threat. If the risk response plan was not followed, the mitigation steps were not executed, leaving safety risks unaddressed and resulting in the observed safety concerns on the building project.

Exploiting is a positive risk (opportunity) response strategy used to ensure an opportunity occurs; it is not applicable to safety threats or negative risks.

While communication gaps can contribute to poor adherence, the question specifies the issue is non-adherence to the plan itself, pointing directly to a failure in executing mitigation actions rather than a communication breakdown.
