Answer:
B) All three companies employ deliberate strategies.
Explanation:
A deliberate strategy is a planned strategy, that means that management had had previously developed the strategy and then started to carry on its plan (i.e. planning before acting).
The difference with an emergent strategy is that emergent strategies are continuous process of testing and learning, and not necessarily following a formal plan.
All three companies seem to follow a predetermined strategy, therefore they all employ deliberate strategies.
