Correct Answer: baaba


Solution : Given:
a _ aabb _ _ ab _ b _

To fill the series we have to divide the series – a _ / aabb /_ _ab _ b /_
Let's check each option –
First option: baaaa; ab / aabb / aaabab / a (No repeated pattern has been found.)
Second option: babab; ab / aabb / ababab / b (No repeated pattern has been found.)
Third option: baaba; ab / aabb / aaabbb / a (Here, the number of a and b are increased by one.)
Fourth option: bbaaa; ab / aabb / baabab / a (No repeated pattern has been found.)

So, the series is abaabbaaabbba. Hence, the third option is correct.
