Answer:
B) Making the value of the company increase by generating increasing revenues and profits
Step-by-step explanation:
The main responsibility of a manager is to increase the company's value in order to increase the wealth of its owners. Of course this should be done in a legal way, e.g. a drug lord that makes millions can't be considered a good businessperson. The responsibility of a manager do not end there, they also have a duty with all the stakeholders of the company, starting with the employees, the government, the environment, their customers, and society as a whole.
