Final answer:

The term 'population' in the SQL statement is an attribute that represents the population value of each city. Thus the correct option is the D. attribute. It's a column in the 'city' table, the command is grouping states by their average population and selecting with an average population greater than 250,000.

Explanation:

In the given SQL statement, the term 'population' is referred to as an attribute. An attribute is a characteristic or property of an entity in a database and it is a column in a table. Population is a column in the table 'city' which holds values related to the population of different cities.

The 'select' clause is used to specify the attributes to be retrieved from the database, while the 'group by' clause is used to group the results based on a specific attribute, which is 'state' in this case.

The command is applying an average operation on the population attribute of each state. It then groups these states by the average population and selects only those states where this average population is greater than 250,000.
