One characteristic of an insurance contract is that both parties must perform certain acts to make the contract legally enforceable. This is called: A. Personal aspect; B. Aleatory; C. Executory; D. Utmost good faith

The correct answer is D. Utmost Good Faith. This is a basic principle of insurance contracts which requires that both parties in the contract must act in a manner that is honest, open and in good faith towards each other. All parties must disclose any and all information which would be pertinent to the risk or the outcome of the contract, to ensure that all parties are able to make an informed, honest decision when agreeing to the contract.
