Step-by-step explanation:
The correct answer to this question is c) The aircraft owner. The aircraft owner is responsible for ensuring that applicable airworthiness directives (ADs) are carried out on their aircraft.
An airworthiness directive is a regulation issued by the aviation authority (in this case, Transport Canada) that mandates specific actions to be taken on an aircraft to correct an unsafe condition or to comply with a new requirement.
For example, if an AD is issued for a certain component of the aircraft, such as the engine or landing gear, the aircraft owner is responsible for making sure that the necessary inspections, repairs, or modifications are carried out by a qualified maintenance organization (AMO) or an approved aircraft maintenance engineer (AME).
