right I do this against the scot.emp table as follows:

SQL> column empl format a80
SQL> CREATE OR REPLACE FUNCTION my_emp_list(m_deptno IN NUMBER) RETURN VARCHAR2 AS
  2   m_str VARCHAR2(100) := '';
  3  BEGIN
  4   FOR emp_cur IN (SELECT ename FROM emp WHERE deptno = m_deptno) LOOP
  5     IF m_str IS NOT NULL THEN
  6       m_str := m_str || ',';
  7     END IF;
  8     m_str := m_str || emp_cur.ename;
  9   END LOOP;
 10   RETURN m_str;
 11  END;
 12  /

Function created.

SQL> SELECT deptno, my_emp_list(deptno) empl
  2  FROM emp
  3  GROUP BY deptno
  4  /

If your data is as follows
and you have only values JAN...DEC for col4, then you can use a query like this for getting what you want.

select id, trim(',' from
max(decode(month,'JAN',month||','))||
max(decode(month,'FEB',month||','))||
max(decode(month,'MAR',month||','))||
max(decode(month,'APR',month||','))||
max(decode(month,'MAY',month||','))||
max(decode(month,'JUN',month||','))||
max(decode(month,'JUL',month||','))||
max(decode(month,'AUG',month||','))||
max(decode(month,'SEP',month||','))||
max(decode(month,'OCT',month||','))||
max(decode(month,'NOV',month||','))||
max(decode(month,'DEC',month))) months
from c
group by id, name, id2
/

It will return results like:
SQL> select * from c;

        ID NAME                                  ID2 MONTH
---------- ------------------------------ ---------- ------
         1 ABC                                    10 JAN
         1 ABC                                    10 FEB
         1 ABC                                    10 MAR
         2 XYZ                                    10 MAY
         2 XYZ                                    10 DEC

SQL> select id, trim(',' from
  2  max(decode(month,'JAN',month||','))||
  3  max(decode(month,'FEB',month||','))||
  4  max(decode(month,'MAR',month||','))||
  5  max(decode(month,'APR',month||','))||
  6  max(decode(month,'MAY',month||','))||
  7  max(decode(month,'JUN',month||','))||
  8  max(decode(month,'JUL',month||','))||
  9  max(decode(month,'AUG',month||','))||
 10  max(decode(month,'SEP',month||','))||
 11  max(decode(month,'OCT',month||','))||
 12  max(decode(month,'NOV',month||','))||
 13  max(decode(month,'DEC',month))) months
 14  from c
 15  group by id, name, id2
 16  /

        ID MONTHS
---------- ----------------------------------
         1 JAN,FEB,MAR
         2 MAY,DEC
