Which of the following terms describes a situation that is likely to lead to sudden change or violence?

The term "volatile" effectively describes a situation that is likely to lead to sudden change or violence due to its connotation of instability and unpredictability. In many contexts, such as finance or politics, volatility is characterized by rapid fluctuations, which can create an environment where events may escalate quickly and unexpectedly. This implies a risk of turmoil or conflict, making it a fitting choice for describing scenarios where sudden shifts may occur.

In contrast, terms like "stable," "predictable," and "safe" convey a sense of security and lack of disturbance. A stable situation is one that remains consistent over time without significant changes, while predictable suggests that outcomes can be foreseen with a degree of certainty. The term safe indicates a lack of immediate danger or threat. Therefore, these options do not capture the essence of a scenario likely to turn tumultuous or violent as effectively as "volatile."
