To answer this question, you need to understand the components required to connect to an Oracle database using SQL*Plus.
Let's go through each option to understand why it is correct or incorrect:
Option A) The SQL*Plus Keyword - This option is incorrect because you need to specify the SQL*Plus keyword, such as "sqlplus", to indicate that you want to use SQL*Plus for database connection.
Option B) The username - This option is correct because you must specify a valid username to connect to the Oracle database. The username identifies the user account that you want to use for the connection.
Option C) The password - This option is correct because you must provide the correct password associated with the specified username to establish a successful connection to the Oracle database.
Option D) The database name - This option is incorrect because you must specify the database name as part of the connection information. The database name identifies the specific Oracle database you want to connect to.
The correct answer is D) The database name. This option does not indicate a component you must specify when logging into the Oracle database using SQL*Plus.
