Correct Answer: B
Explanation:
Alphabet Series - A B C D E F G H I J K L M N O P Q R S T U V W X Y Z
First two letters are BC in reverse i.e. CB. It is a term of 2 alphabets so next 2 alphabets D and E are skipped.
Next term is FGH in reverse i.e. HGF. It is a term of 3 alphabets so next 3 alphabets I J and K are skipped.
Next term is LMNO in reverse i.e. ONML. It is a term of 4 alphabets so next 4 alphabets P Q R and S are skipped.
Next term should be TUVWX in reverse i.e. XWVUT. It should be 5 alphabets term.
