Answer:
Th answer is: D) Length of time the core competence has existed
Explanation:
Your competitive advantage will last as long as the competition can´t successfully imitate your strategies. No competitive advantage is eternal. At some point the competition will be able to overcome your competitive advantages either by imitation or by developing new products or services due to environmental changes. Companies must always develop additional competitive advantages so that they are ahead of their competition.
For example, in the future, electric cars will make cars with internal combustion engines obsolete. So no matter how good a BMW is right now, in the future if they can´t develop good electric cars they will go out of business.
