Show answer & explanation

Correct answer: A

To add a new column to an existing table in SQL, the ALTER command is used. The syntax is: ALTER TABLE table_name ADD column_name data_type; This command modifies the table structure by adding a new column. The UPDATE command is used to modify existing data, not to change the table structure. The CHANGE command is not a standard SQL command for adding columns. The ADD NEW command is not valid syntax in SQL. Therefore, the correct command is ALTER.
