In Hanks V

In Hanks v. McNeil Coal Corporation (the father sold property to a coal company, and the son, conservator of the father's estate, was trying to invalidate the sale) , the court held that

A) the contract could be voided because the son, as conservator of the father's estate, had proved his father was insane at the time of the contract.
B) the real property sale was voidable because the sale was directly connected with the horse medicine business.
C) the contract was void because the father had been adjudicated insane prior to signing the contract.
D) the son had failed to prove the father's mental problem affected his conduct with regard to the contract.
