  1. Use an asterisk for the path property

  3. Set the "unknown" property of the mapping to "true"

  4. Set the "missing" init-param of the ActionServlet to the mapping's path

C Correct answer
Explanation

In Struts 1.x, to create a default/fallback ActionMapping that handles requests not matching any other mapping, you set the 'unknown' property to true on that mapping (option C). This is commonly used for 404-style handling. Option A is incorrect, B uses wrong property name, and D references a non-existent init-param.
