Consider the sequence AB_CC_A_BCCC_BBC_C that follows a certain pattern. Which one of the following completes the sequence?

Correct Option (3)

The given sequence is AB_CC_A_BCCC_BBC_C. Upon careful observation, the sequence follows a repeating block pattern of 'ABB CCC'.

When the blanks are filled with the letters from Option 3 (B, C, B, A, C), the sequence becomes:

• AB(B) CC(C) A(B) BCCC (C) BB(A) C(C)

This arrangement completes the sequence as 'ABB CCC ABB CCC ABB CCC', thereby maintaining the established pattern.

Incorrect Options:

Options 1, 2, and 4 do not complete the sequence according to the identified repeating pattern 'ABB CCC'. Substituting the letters from these options into the blanks would disrupt the consistent block structure of the series.
