An illusory promise refers to a situation where a statement or commitment lacks absolute commitment or certainty due to indefinite conditions or vagueness, thus failing to create a binding obligation. The scenario of a pledge to cook only if in the mood exemplifies this concept because it is contingent upon the individual's subjective emotional state. Since the promise is dependent on the mood, it does not impose a real duty or obligation on the promisor; they could simply choose not to fulfill the promise without any repercussions.

In contrast, the other scenarios do involve some level of commitment or definitive conditions that could result in a binding obligation. For instance, promising to donate only if funds permit implies a condition based on financial capability, but there is still a promise in play that could be enforceable if the funds are available. The commitment to work if paid on time and the guarantee to attend if not busy contain elements that suggest a level of obligation should the stipulated conditions be met. However, the pledge in question remains wholly contingent on an emotional state, illustrating an illusory nature.
