Answer:
b. Italy
Step-by-step explanation:
Even though this % doesn't apply to all corporations, it is still a very small number of shareholders that control corporations (and their board) on average. We can compare this situation to the American normality, where any shareholder that owns 5% or more of a large corporation is considered a major shareholder and must report himself/herself to the SEC as such.
In the US, many of the corporations would be considered closed corporations. The smaller the number of shareholders with large decision power, the less small shareholders can do.
