Derick was acting in a very bizarre manner for quite some time, and a court of law finally declared him to be incompetent. He is now under the full care of his son.Without informing his son, Derick rented the Opera House which has a capacity of 12,000 in order to hold the Championship party for the Golden State Warriors.Most likely, this rental agreement would be:

a.A void contract,

b.A quasi contract,

c.A bilateral contract,

d.An implied contract.
