        System.out.println("static = " + sta + "tic");
    }

    public static int recurse(int pub, int lic)
    {
        if (pub % 13 == 0)

User comments below. All of them might not be correct.

ans:D
because method recruse(ma.in) is not defined in the class thats why it gives complile time error
and if we change recruse to recurse()  also it give  runtime error called stack over flow  error
it go infinite recursive because of  recurse(pab++,lic/2) this funtion call

if we want excecute  this program succesfully
changes are recruse() to recurse() and
in method recurse()
recurse(pab++,lic/2) to recurse(++pab,lic/2)

ans c.initially ma ,in assigned with 35 ,67.sta assigned with recrush() method.here we used different names as parameters in function definition. if condition satisfied only ma is completely divided by 13.so return method recursively calls this method upto it get value 35 to 39.1st tim pub++ is 36, lic/2=33 passed 2nd time pub is 37 ,lic/2=16 these values passed, 3rd time pub is 38,lic/2=8,4th tim pub++ is 39,lic/2 is 4.this time if condition passed. it returns pub+lic=39+4=43.finally sop prints static 43tic
