• A. a b a a b
• B. b b a b a
• C. b b a b b

Answer 1

The correct option is A a b a a b

Answer is option (A)
We will divide the series with three alphabets making one part of series.
a _ _ /b _ a /_ a b/ _ a a
The series is in the form of aab/ baa/ aab/ baa where the terms aab and baa are repeated alternately.
Hence abaab is correct answer.
