(C) To evaluate the limit $\lim _{x \rightarrow \infty}\left(\frac{8 x^2+5 x+3}{2 x^2-7 x-5}\right)^{\frac{4 x+3}{8 x-1}}$,we first find the limit of the base as $x \rightarrow \infty$: $\lim _{x \rightarrow \infty} \frac{8 x^2+5 x+3}{2 x^2-7 x-5} = \lim _{x \rightarrow \infty} \frac{8 + \frac{5}{x} + \frac{3}{x^2}}{2 - \frac{7}{x} - \frac{5}{x^2}} = \frac{8+0+0}{2-0-0} = 4$. Next,we find the limit of the exponent as $x \rightarrow \infty$: $\lim _{x \rightarrow \infty} \frac{4 x+3}{8 x-1} = \lim _{x \rightarrow \infty} \frac{4 + \frac{3}{x}}{8 - \frac{1}{x}} = \frac{4+0}{8-0} = \frac{4}{8} = \frac{1}{2}$. Therefore,the limit is $4^{\frac{1}{2}} = 2$.

$\lim _{x \rightarrow \infty}\left[\frac{8 x^2+5 x+3}{2 x^2-7 x-5}\right]^{\frac{4 x+3}{8 x-1}} = $
