Answer :
Answer: a. the narrow view, or invisible hand theory
Explanation:
When it comes to the narrow view theory of corporate social responsibility, companies put one thing above all else, the maximisation of shareholder wealth.
Any activity that would help them do so - legally - is considered fair game even if it leads to adverse effects. Corruptco is therefore adhering to this theory because they are polluting the the local river to maximize shareholder value.
