Kosal,

Refrain from using capital variables; some of them are reserved
(C,D,E,I are reserved!). This very specific example could be solved in
the following way:

myfunc[a_, b_] := Prepend[b, a[[-1]]]
list1 = {{a, b, c}, {d, e, f}, {g, h, i}};
list2 = {{1, 2}, {3, 4}, {5, 6}};
MapThread[myfunc, {list1, list2}]

Best Regards,

Sander
