AI Explanation

To answer this question, we need to understand the different types of JDBC drivers and their compatibility with applet and servlet code.

Option A) Both Type 1 and Type 2 - This option is incorrect because neither Type 1 nor Type 2 JDBC drivers can be used in either applet or servlet code.

Option B) Both Type 1 and Type 3 - This option is incorrect because although Type 1 JDBC drivers can be used in applet or servlet code, Type 3 JDBC drivers cannot.

Option C) Both Type 3 and Type 4 - This option is correct because both Type 3 and Type 4 JDBC drivers can be used in either applet or servlet code.
