The second letter of the first, second, third, fourth terms are respectively moved one, two, three and four steps forward to obtine the corresponding letter of the subsequent term. So, the second letter in the missing term
will be O. The third letter is alternately moved two and three steps forward to obtain the corresponding letter of the subsequent term. So, the third letter in the missing term will be L. Thus, the missing term is QOL. Hence, the answer is (a).The third letters of the first, second, third, fourth and fifth terms are moved seven, eight, nine, ten and eleven steps forward respectively to obtain the third letter of the successive terms. Thus, the missing term would be ZKW. Hence, the answer is (a).
