Which of the following contracts contains unequal exchanges of value?

An aleatory contract is characterized by an unequal exchange of value, where one party’s cost is contingent upon an uncertain event occurring, such as in insurance agreements. In such contracts, the amount paid by one party (the insurer) is typically much greater than the premium paid by the other party (the insured), particularly if a significant loss occurs. This element of chance means that the benefits received by one party may greatly outweigh what is given in return, depending on the outcome of a specified event.

In contrast, personal contracts generally involve mutual obligations and do not inherently rely on uncertain circumstances to define their value exchange. Unilateral contracts also don’t specify unequal values since only one party is bound to perform, while the other enjoys a potential benefit without an obligation. Conditional contracts involve adhering to specific conditions which must be fulfilled for the exchange to occur, thereby maintaining balance rather than creating an unequal exchange of value. Thus, the defining feature of an aleatory contract lies in its inherent uncertainty and the unequal value exchange it permits, making it the correct choice.
