85. The Medical Information Bureau (MIB)

Answer: D

Explanation:

The Medical Information Bureau (MIB) satisfies all of the above.

The MIB is indeed a nonprofit agency that supports life insurance companies in underwriting, provides member companies with critical information regarding insurability, and requires authorization from applicants to share their information. Therefore, it encompasses all the functions described in the options.

A) Is a nonprofit agency supported by life insurance companies to aid in underwriting.

This statement is correct as the MIB operates as a nonprofit organization that assists life insurance companies in the underwriting process by providing relevant data. However, this option alone does not capture the complete role of the MIB.

B) Supplies member companies with information concerning the insurability of proposed insureds.

This option accurately describes one of the primary functions of the MIB, which is to provide member companies with information that helps them assess the insurability of applicants. While correct, it does not encompass all aspects of the MIB's operations.

C) Must be authorized by the applicant to give information to member companies.

This statement is also true, as the MIB requires explicit consent from applicants before sharing their information with member companies. However, this alone does not provide a complete picture of the MIB's role.

D) Satisfies all of the above.

This option is correct because it combines all the previous statements into a comprehensive understanding of the MIB's functions, including being a nonprofit agency, supplying information on insurability, and requiring applicant authorization.

Conclusion

The correct answer, D, encapsulates the full scope of the MIB's operations, confirming its role as a nonprofit aiding in underwriting, supplying crucial information, and adhering to authorization protocols. The other options, while accurate in their own right, only represent partial truths and do not provide the complete context necessary to understand the MIB’s involvement in the insurance process.
