How would one describe a situation that is perilous?

A perilous situation is characterized by a significant risk or danger, which aligns perfectly with the description of being risky and dangerous. When something is described as perilous, it implies that it poses a threat or an imminent chance of harm or negative outcomes. This could relate to physical danger, such as navigating through treacherous terrain or engaging in activities that could lead to serious injury. Therefore, recognizing the inherent risks in these scenarios is crucial to understanding why it is described this way. The other descriptions, while they pertain to different contexts, do not capture the essence of danger or risk associated with a perilous situation. It is the association of risk and the potential for harm that defines the term and makes the chosen answer the most suitable.
