Answer:
The correct answer is letter "D": Both A and B, but not C.
Explanation:
Highly efficient companies are characterized by giving employees resources so they can fulfill their corporate personal achievements and align them with the overall company's objectives. Firms achieve that stage when employees' voice is heard, they have enough freedom to make decisions on their duties, compensation is stable, and promotion opportunities are available.
All the factors mentioned above increase the corporation's possibilities of boosting their productivity levels which eventually is traduced in higher profits.
