Final answer:
The specific bi-annual fee for renewing a Real Estate Salesperson License cannot be determined from the provided reference information on political contributions; licensing fees vary by state.
Step-by-step explanation:
The question regarding the bi-annual fee to renew a Real Estate Salesperson License does not directly match the provided reference information that pertains to individual and multicandidate political contributions. Therefore, without the specific context of real estate licensing fees, which can vary by state or regulating body, it is not possible to accurately determine the bi-annual fee. Typically, the cost associated with license renewal in the real estate industry could fall under any of the options provided (a) $50, (b) $75, (c) $100, or (d) $125, but this is generally determined by the real estate commission or licensing board of the specific state.
