Let $\left(1+x+x^{2}\right)^{2014}=a_{0}+a_{1} x+a_{2} x^{2}+a_{3} x^{3}+\ldots . .+a_{s+28} x^{4028}$ and let
$$
\begin{array}{l}
A=a_{0}-a_{3}+a_{6}-\ldots \ldots+a_{4026} \\
B=a_{1}-a_{4}+a_{7}-\ldots \ldots .-a_{4027} \\
C=a_{2}-a_{5}+a_{8}-\ldots \ldots .+a_{4028}
\end{array}
$$
Then
- A$|A|=|B|>|C|$
- B$|A|=|B| < |C|$
- Correct answerC$|A|=|C|>|B|$
- D$|A|=|C| < |B|$
Hence, the correct answer is option: 'C'.
