$f:N\to N$ is defined as

$f\left(n\right)=\left\{\begin{array}{cc}\begin{array}{l}2,n=3k,\\ 10-n,n=3k+1\\ 0,n=3k+2,\end{array}& \begin{array}{l}k\in Z\\ k\in Z\\ k\in Z\end{array}\end{array}\right.$

then $\left\{n\in N:f\left(n\right)>2\right\}=$

• A

  {3,6,4}

• B

  {1,4,7}

• C

  {4,7}

• D
