Correct Option: A

AI Explanation

To answer this question, you need to understand the syntax for inserting values into a table using the INSERT statement. Let's go through each option to understand why it is correct or incorrect:

Option A) INSERT INTO r4r_team (id, username, exp) VALUES (1, 'r4r01', '2') - This option is correct. It follows the correct syntax for inserting values into the r4r_team table. The column names (id, username, exp) are specified, followed by the keyword VALUES, and then the corresponding values (1, 'r4r01', '2').

Option B) INSERT INTO r4r_team VALUES (1, 'r4r01', '2') - This option is incorrect. While it inserts values into the r4r_team table, it does not specify the column names. It assumes that the values are being inserted in the order of the columns defined in the table, which can lead to errors if the order is different.

Option C) INSERT INTO r4r_team (id, username, exp) VALUE (1, 'r4r01', '2') - This option is incorrect. The correct keyword is VALUES, not VALUE. This is a syntax error.

Option D) INSERT INTO table r4r_team (id, username, exp) VALUE (1, 'r4r01', '2') - This option is incorrect. The correct syntax does not include the keyword "table" before the table name. Additionally, the correct keyword is VALUES, not VALUE.

The correct answer is A. This option is correct because it follows the correct syntax for inserting values into the r4r_team table, specifying the column names and corresponding values.
