C) A, 13                  

D)       B, 14

E) None of these

Correct Answer: A

Solution :

Explanation: Option (a) is correct because in the series numbers and letters take place alternately. Every next number decreases by 2. Let us see: \[21-2\text{ }=\text{ }19\] \[19-2\text{ }=\text{ }17\] \[17-2\text{ }=\text{ }15\] \[15-2\text{ }=\text{ }13.\] If you see the letters, you find that every next letter takes places skipping one letter in reverse order. Let us see: Rest of the options is incorrect because of the correctness of option (a).
