The correct answer is D. All of the above.
A free look period is a period of time, usually 10 to 30 days, during which a policyholder can cancel a life insurance policy and receive a full refund of the premium paid. The purpose of the free look period is to allow the policyholder to review the policy and make sure it is what they want before they are locked into a long-term contract.
A passport and school certificate are both standard proofs of age. A passport is a document issued by a government that identifies the bearer as a citizen of that country. A school certificate is a document issued by a school that certifies that the bearer has completed a certain level of education.
A ration card is a document issued by a government that entitles the bearer to purchase rationed goods. Ration cards are not typically considered to be standard proofs of age.
However, there are some cases in which a ration card may be accepted as proof of age. For example, if you are applying for a government benefit that requires proof of age, you may be able to use a ration card as one of the documents required to prove your age.
Ultimately, the decision of whether or not to accept a ration card as proof of age is up to the individual or organization that is requesting the proof.
