Final answer:
An oral agreement may be enforceable depending on the specific details of the agreement and the presence of certain legal elements.
Step-by-step explanation:
An oral agreement is a verbal agreement between two parties that may not be legally enforceable. In order for a contract to be enforceable, it generally requires certain elements such as an offer, acceptance, consideration, and intention to create legal relations.
In this scenario, the enforceability of the agreements depends on the specific details of each agreement. A. The sale of a new car could be enforceable if there is a clear offer, acceptance, and consideration between the parties. B. A lease of an apartment for one year can be enforceable if there is a mutual agreement, consideration, and intention to create legal relations. C. A six-month loan of $1000 may be enforceable if there are clear terms of borrowing, repayment, and an intention to create a legally binding agreement.
Based on this information, options A, B, and C could potentially be enforceable.
