Which of the following is a synonym for "ill-prepared"?

The term "ill-prepared" refers to a state of not being ready or adequately equipped for a particular situation. Choosing "unfit" captures this essence, as it signifies a lack of suitability or readiness for a certain task or challenge. When someone is unfit, it implies that they are not in the right condition or preparedness to handle demands effectively.

In contrast, the other terms—"ready," "equipped," and "competent"—all suggest a positive level of preparedness or ability, which directly opposes the meaning of "ill-prepared." Thus, "unfit" is the most fitting synonym in this context, highlighting a lack of readiness.
