Final answer:
Real estate license expiration dates vary by state and are often determined by the date of issuance or other criteria set by the local real estate commission. They generally do not expire on fixed dates for all jurisdictions. Therefore, for the specific expiration date of a real estate license, one should consult their local real estate regulatory authority.
Step-by-step explanation:
The expiration dates for real estate licenses vary by state and regulatory body. However, they generally do not expire on arbitrary fixed dates across all jurisdictions. Instead, expiration dates may be set on an annual basis calculated from the date of issuance, or on a biennial basis, or another term set forth by the regulating agency.
Additionally, some jurisdictions may set expiration dates on the licensee's birthday or another assigned date that may not coincide with the end-of-month dates listed in your choices (a. January 31st, b. March 31st, c. June 30th, d. December 31st).
One must check with the relevant state real estate commission or licensing board to determine the specific expiration date for a real estate license in that jurisdiction. Due to the variation in licensing laws, the answer can differ significantly between locations.
