Let $\omega \neq 1$ be a complex root of unity, find the possible value(s) of $n$ such that $(3-3\omega+2\omega^2)^{4n+3}+(2+3\omega-3\omega^2)^{4n+3}+(-3+2\omega+3\omega^2)^{4n+3}=0$ $\begin{array}{ll} (1) \, 1 \quad \quad \quad \quad \quad \quad \quad \quad & (2) \, 2 \\ (3) \, 4 & (4) \, 5 \end{array}$ Note:

• Submit your answer as the increasing order of the serial numbers of all the correct options.

• For eg, if your answer is $(1),(2)$, then submit 12 as the correct answer, if your answer is $(2),(3),(4)$, then submit 234 as the correct answer.
