Correct Answer: adbcbd


Solution : Given:
a_bc_a_bcdabc_da_cd_

First, divide the series before filling it →a_ / bc_a / _b / cdab / c_ / da_c / d_
Now, check the order of the letters in the given series→ a a / bc d a / b b / cdab / c c / da b c / d d
(In every alternate part, starting from the first, the letters appear twice in sequential order; starting from the second, the letters are being shuffled i.e. the second letter moves to the first position followed by the third and the fourth letters, and the first letter shifts to the fourth position.)

The series becomes→aabcdabbcdabccdabcdd. Hence, the second option is correct.
