Correct answer: D

In embedded SQL, the SELECT INTO statement is used to fetch data from a database and store it directly into host variables. This allows the application to retrieve specific data from a table and use it in the host program. The syntax is: SELECT column1, column2 INTO :host_var1, :host_var2 FROM table_name WHERE condition; The INTO clause specifies the host variables where the retrieved data will be stored. This is essential for retrieving data in a structured way within a host language like C or COBOL.
