To answer this question, you need to understand the purpose of each clause in a SQL query.
The WHERE clause is used to filter rows based on a condition. It is used to exclude individual rows from the result set based on a specific condition.
The HAVING clause, on the other hand, is used to filter groups based on a condition. It is typically used with the GROUP BY clause and is used to exclude groups from the result set based on a specific condition.
The RESTRICT clause does not exist in standard SQL syntax, so it is not the correct answer.
The GROUP BY clause is used to group rows based on one or more columns. It is used to create groups in the result set based on the specified columns.
The ORDER BY clause is used to sort the result set based on one or more columns. It is not used to exclude any rows or groups from the result set.
Therefore, the correct answer is B) HAVING. The HAVING clause is used to exclude groups from the result set based on a specific condition.
