Correct Answer: cacab


Solution : Given:
_ab _ b _ bc _ ca _

To fill the series we have to divide the series – _ab / _ b _ / bc _ / ca _
Let's check each option –
First option: accbb; aab / cbc / bcb / cab (No repeated pattern has been found.)
Second option: abcca; aab / bbc / bcc / caa (No repeated pattern has been found.)
Third option: cacab; cab / abc / bca / cab (In each part the letters are being shuffled – the first letter is moved to the third position in the next part and the second and third letters are moved to the first and second positions respectively.)
Fourth option: abacb; aab / bba / bcc / cab (No repeated pattern has been found.)

So, the series becomes→cababcbcacab. Hence, the third option is correct.
