Final answer:
A risk statement consists of an issue and the possible outcome if the issue occurs, and is significant for risk management and analysis. Option c.
Step-by-step explanation:
A risk statement is typically composed of two main elements: an issue (sometimes referred to as a threat or hazard) and the potential impact or possible outcome if that issue occurs. A well-structured risk statement informs an organization of what could happen (the issue) and what the result might be (the possible outcome), which is essential for implementing effective risk management strategies. Option c.
Risk, as defined by the National Research Council (2002), is the product of the likelihood of an event or process and its consequences. Thus, in the context of environmental management, risk analysis techniques are crucial. They not only consider the biology of species but also encapsulate environmental damage, social and economic impacts, and public health concerns, as well as evaluate the feasibility of control or eradication measures, such as those required for preventing plant invasions.
