Multiple Choice

Perform the indicated operation and express in lowest terms.
- $\frac{16 s^{2}+8 s t+t^{2}}{2 s^{2}-9 s t-5 t^{2}} \cdot \frac{2 s^{2}-11 s t+5 t^{2}}{t^{2}+3 s t-4 s^{2}} \div \frac{8 s^{2}-2 s t-t^{2}}{2 s^{2}+3 s t+t^{2}}$

A) $\frac{t+s}{t-s}$

B) $\frac{(\mathrm{t}+4 \mathrm{~s}) }{(\mathrm{t}+\mathrm{s}) (\mathrm{t}-\mathrm{s}) }$

C) 1

D) $\frac{(t+4 x) ^{2}(2 x-t) ^{2}}{(4 s+t) ^{2}\left(t^{2}-s^{2}\right) }$
