Answer: d. mike cannot disaffirm because he has already ratified the contract
Explanation:
When signing deals it's important to consider long term, this helps to make the best decision in any and most scenario. Most deals signed too cannot be reversed or change or adjusted because it'll affect the policy of the organization and won't be health for them. Mike has agreed to buy a property through a spread payment plan, changing the deal now after some years will not be possible as it distorts the plan intially agreed and goes against the policy of the organization selling the home.
