Final answer:
In SQL, the column list in the CREATE TABLE command must be enclosed in option a) parentheses.
Step-by-step explanation:
The column list of the CREATE TABLE command must be enclosed in parentheses (A).
When you create a table in SQL, the syntax typically includes the CREATE TABLE command followed by the table name and a list of columns, with each column defined by a name and a data type. This list of columns with their data types must be enclosed within parentheses to separate them from the rest of the SQL statement and to define them as part of the structure of the new table.
