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.
Jesus was a man who, according to the various books of the Bible, was the son of God. They speak of their passage through the world as an act of God´s redemption for the world, since sin had generated a state of crisis that could even destroy the social foundations, and this problem could not be solved even by the rulers of the epoch.
Even personally I do not believe in Jesus, the simple fact Christianity is a religion which allows the people to do the correct and help the others is so respectable.
