Final answer:
A real estate license is required for a trustee overseeing the sale of a foreclosed property in California, while selling one's own home, hosting open house weekends, or managing a personal apartment complex do not require a license. Correct option is B.
Step-by-step explanation:
According to California law, a real estate license is required for activities that involve selling, leasing, or managing real estate owned by others. With this in mind, Option B would require a real estate license as a trustee overseeing the sale of a foreclosed property is managing the sale of a property on behalf of the owner or lender.
On the other hand, Options A, C, and D would not require a real estate license. A person selling his or her own home (Option A) is considered a private sale and does not involve representing others. Similarly, a real estate secretary hosting open house weekends (Option C) is not involved in any selling or leasing activities. Finally, a person managing the apartment complex he or she lives in (Option D) would not need a real estate license as they would be managing a property they own and not representing others.
