A letter series is given with blanks:
$C\_\ BBA\_\ CAB\_\ AC\_\ AB\_\ AC$
The missing letters (left to right) are given by which option?
🎥 Video solution / Text Solution of this question is given below:
Filling with **ACBCB** gives
$C\color{blue}{A}BBA\color{blue}{C}CAB\color{blue}{B}AC\color{blue}{C}AB\color{blue}{B}AC$
Grouping in 3’s: $[CAB][BAC][CAB][BAC][CAB]$ — a neat repetition of the block “CAB, BAC”.
Other choices break this pattern.
