Solution

The correct answer is b. UPDATE.

In Java, to update data in a database table, you use the UPDATE SQL statement. The general syntax is:

UPDATE table_name
SET column1 = value1, column2 = value2, ...
WHERE condition;

Here, table_name is the name of the table where you want to update data. column1, column2 are the columns of the table that you want to update. value1, value2 are the new values for the respective columns. The WHERE clause specifies which record or records that should be updated. If you omit the WHERE clause, all records will be updated.
