____ is an example of an Artistic filter.

Fill in the code below in the underline:

``` public class Test { public static void main(String[] args) { Test test = new Test(); test.setAction(______________________________); } public void setAction(T1 t) { t.m(); } } interface T1 { public void m(); }``` a. () -> System.out.print("Action 1! ") b. (e) -> System.out.print("Action 1! ") c. System.out.print("Action 1! ") d. (e) -> {System.out.print("Action 1! ")}
