Final answer:
In Florida, a child needs to be at least 18 years old to sign a life insurance application, which corresponds to the age of legal majority.
Step-by-step explanation:
In Florida, the legal age for an individual to sign a life insurance application is 18 years. This age corresponds to the age of majority in many jurisdictions across the United States, including Florida. At the age of 18, individuals attain the legal rights and responsibilities of adulthood. In Florida, persons below the age of 18 are generally classified as minors and lack the legal capacity to enter into binding contracts, which includes applications for life insurance.
Exceptions to this rule may exist if parental consent is obtained or if the individual has been emancipated through a court order. This legal framework is in place to ensure that individuals have the maturity and legal capacity necessary to make significant financial decisions, such as entering into life insurance contracts. Therefore, the correct answer to the question is indeed option c) 18.
