B)        M 20

C) L 19                    

D)        20 O

E) None of these

Correct Answer: D

Solution :

Explanation: Option (d) is correct because in the given series letters and numbers take place alternately. Every next letter takes place skipping 0, 1, 2 and 3 letters respectively in forward order. Let us see: If you see the numbers, you find that every next number increases by 3. Rest of the options is incorrect because of the correctness of option (d).
