Justin, an adult, contracts with Helm Services to purchase, in installments over a period of six years, a very large quantity of services that he will probably never need. Although Justin understands what he is doing when he enters the contract, he has a mental condition that impairs his ability to act in a reasonable and rational way. Under the Restatement:

Select one:

a.

Justin cannot avoid the contract if Helm Services had no reason to suspect Justin's incompetency.

b.

Justin cannot avoid the contract if the terms are fair.

c.

Justin can only avoid the contract if the terms are grossly unfair.

d.

Justin's contract is voidable at his option while it is entirely executory.
