What term best describes someone who is liable to injury or hurt?

The term that best describes someone who is liable to injury or hurt is "vulnerable." This word indicates a susceptibility to harm, either physically, emotionally, or mentally. Vulnerability implies that an individual may be at risk or exposed to potential dangers or adverse situations that could lead to harm.

In contrast, "resilient" refers to the ability to recover quickly from difficulties or to withstand stress, indicating strength rather than susceptibility. "Stable" suggests a firm or steady state, which does not imply a likelihood of being hurt. "Protected" indicates the presence of safeguards that prevent harm from occurring, thus opposing the idea of being liable to injury. Therefore, "vulnerable" is the most fitting term to describe someone likely to face injury or hurt.
