An Employee from Dr

An employee from Dr.Don's Automobile Hospital,Inc.made a house call to Horner's home to repair his car.It was repaired in Horner's garage.When Horner defaulted on the bill,Dr.Don went to his house to take possession of the car,claiming that the corporation had a lien on the car by virtue of the work performed on it.On the basis of these facts,it can be said that:

A) the employee is entitled to the possession of the car because he was the one who performed the repairs on the car.
B) Dr.Don is justified in his actions as the corporation did have a lien on the car by virtue of the work performed on it by its employee.
C) the corporation has no lien on the car because the employee did not notify Horner at the time of the repairs that a lien would be claimed.
D) the corporation has no lien on the car,because its employee came to Horner's house to make the repairs and so Horner never gave up possession of his car to Dr.Don's.
