To solve this question, the user needs to know the basic syntax and usage of the LIKE keyword in SQL.

The LIKE keyword is used in SQL along with the WHERE clause to search for a specific pattern in a column of a table. The LIKE keyword is used to perform partial matching of strings and can be used with wildcard characters, such as % to represent any number of characters or _ to represent a single character.

Now, let's go through each option and explain why it is right or wrong:

A. ORDER BY clause: This option is incorrect because the ORDER BY clause is used to sort the result set in ascending or descending order based on one or more columns. It does not have any relation to the LIKE keyword.

B. GROUP BY clause: This option is incorrect because the GROUP BY clause is used to group the result set based on one or more columns. It also does not have any relation to the LIKE keyword.

C. JOIN clause: This option is incorrect because the JOIN clause is used to combine rows from two or more tables based on a related column between them. It also does not have any relation to the LIKE keyword.

D. WHERE clause: This option is correct. The LIKE keyword is used along with the WHERE clause to filter the rows in a table based on a specific pattern in a column. The WHERE clause is used to specify the condition that must be met for a row to be included in the result set.

Therefore, the correct answer is: D. WHERE clause.
