Correct Answer: $\frac{2}{9}$

Solution : $\frac{\sqrt{10+\sqrt{25+\sqrt{108+\sqrt{154+\sqrt{225}}}}}}{\sqrt{16+19.25 \times 4^2}}$
$=\frac{\sqrt{10+\sqrt{25+\sqrt{108+\sqrt{154+15}}}}}{\sqrt{4^2(1+19.25)}}$
$=\frac{\sqrt{10+\sqrt{25+\sqrt{108+13}}}}{4\sqrt{20.25}}$
$=\frac{\sqrt{10+\sqrt{25+11}}}{4\ \times 4.5}$
$=\frac{\sqrt{10+6}}{18}$
$=\frac{4}{18}$
$=\frac{2}{9}$
Hence, the correct answer is $\frac{2}{9}$.
