D. all of the above

Explanation:

From the Latin "census", the word census means enumeration. In Ancient Rome the census was made by the censors, and it was carried out every five years, registering all the Roman citizens in it. Registering a slave in the census by his master was a solemn way of granting him freedom. The census played an important role in determining the payment of taxes according to the wealth of each, and the contribution of men to the army.
