What is the correct syntax of the DELETE command in SQL?

The DELETE command in SQL is used to remove existing records from a table based on a specified condition. The correct syntax begins with the keyword DELETE, followed by the phrase FROM, which indicates the table from which the records are to be deleted. This structure is fundamental to how SQL commands are constructed, allowing the database system to understand the action being requested.

In this case, "DELETE FROM table_name" adheres to the SQL standard format, where "table_name" is a placeholder for the actual name of the table from which you want to delete records. Depending on whether you include a WHERE clause afterward, you can specify particular conditions to qualify which records to delete. If no condition is provided, all records in the specified table will be removed.

The other options do not conform to SQL syntax and would not be recognized by SQL databases, making them invalid choices for this command.
