The term that best describes something that is dependable is "reliable." Reliability indicates the quality of being trustworthy or consistent in performing a function or fulfilling an obligation. When something is labeled as reliable, it suggests that it can be counted on to function correctly or to provide accurate results consistently over time, which aligns with the notion of dependability.

In contrast, other terms such as "uncertain," "temporary," and "ambiguous" imply instability or lack of clarity. Uncertain conveys doubt about the outcome, temporary suggests a lack of permanence or reliability over time, and ambiguous indicates a lack of clear meaning or interpretation. These terms inherently conflict with the concept of dependability, making them unsuitable choices in this context.
