[tex]\small \boxed{\begin{aligned}\sf \lim_{x \to \infty } \frac{ {(2x - 1)}^{3} }{(1 - 3x {)}^{3} } &=\sf \lim_{x \to \infty } \frac{ {8x}^{3} - {12x}^{2} + 6x - 1 }{ - {27x}^{3} + {27x}^{2} - 9x + 1 } \\\\ \sf &=\sf - \lim_{x \to \infty } \frac{ {8x}^{3} - {12x}^{2} + 6x - 1 }{ {27x}^{3} - {27x}^{2} + 9x - 1 } \\\\ \sf &= \sf - \frac{8 + 0 + 0 + 0}{27 + 0 + 0 + 0} \\\\ \sf &=\sf - \frac{8}{27} \end{aligned}}[/tex]

Jadi, pilihan yang tepat adalah (C).
