A. When a row is added to the table, the default value for the column will be used if no other value is specified.

A default value is a value that is automatically assigned to a variable or a parameter of a function if no other value is specified. It is a value that is used when no other value is provided. For example, a function may have a parameter that is assigned a default value of 0 if no other value is specified.

If the row is updated with a value for that column, the value will be used instead of the default value. If the row is updated with a zero value for that column, the zero value will be used instead of the default value.
