detailed solution

Correct option is A

Given $\frac{4 + 3 \sqrt{2}}{4 \sqrt{48} - \sqrt{128} + \sqrt{200} - 8 \sqrt{12} + 5 \sqrt{8}}$

$= \frac{4 + 3 \sqrt{2}}{12 \sqrt{2}}$

$= \frac{4 + 3 \sqrt{2}}{16 \sqrt{3} - 8 \sqrt{2} + 10 \sqrt{2} - 16 \sqrt{3} + 10 \sqrt{2}}$

$= \frac{4 \sqrt{2} + 6}{24}$

$= \frac{4 \sqrt{2}}{24} + \frac{6}{24}$

$= \frac{1}{4} + \frac{\sqrt{2}}{6}$

$= a + b \sqrt{2}$

$a = \frac{1}{4}, b = \frac{1}{6}$
