Answer: b.a categorical variable.
Explanation:
In numerical variables, such as rainfall measured in inches or the number of sales in a day, the numbers have a numerical meaning. But a categorical variable is a category such as gender and national origin. It can be represented as a number, like the Social security number, but the numbers won´t have a numerical value. If your SSN is bigger than mine, it doesn´t mean that you are greater or at a different level on a scale, because the numbers are used as categories, not as mathematically meaningful.
Industry (competence) vs. Inferiority
This is a tricky question that requires an explanation, not an true-or false answer!
The thing is, telling your friends what to do is one aspect of leadership, so it would be true. But a lot more is needed for leadership, for example: responsibility and making good informed decisions.
In total, I would say that it's false because a lot more is needed.
