Answer:
B) Frank can reclaim full refund of the amount he paid
Step-by-step explanation:
Disaffirmance is known or regarded as the act of a minor to rescind a contract under the infancy doctrine, either orally, in writing, or by the minor's conduct.
This means that, the minors are allow to cancel most contracts they have
entered into with adults. This principle is known as infancy doctrine, and it is known to be legal. And this can be done by the minors at any time prior to reaching the age of majority.
It should be noted also that, there is another rule known as "Duty of restitution". This rule states that if a minor has transferred money, property, or other valuables to the competent party before disaffirming the contract, that party must place the minor on existing state or agreement.
This means that, Frank as a minor, is supported legally to be refunded in full by John which is a majority or an adult.
