To assign names to the columns in a view, you can do which of the following?
a. Assign aliases in the subquery, and the aliases are used for the column names.
b. Use the ALTER VIEW command to change column names.
c. Assign names for up to three columns in the CREATE VIEW clause before the subquery is listed in the AS clause.
d. None of the above—columns can’t be assigned names for a view; they must keep their original names.
