The correct answer is C. \(\frac{50}{56}\)

Difference between 4\(\frac{5}{7}\) and 2\(\frac{1}{4}\)

\(\frac{33}{7}\) - \(\frac{9}{4}\) = \(\frac{69}{24}\)

The sum of \(\frac{1}{14}\) and 1\(\frac{1}{14}\) + \(\frac{3}{2}\)

= \(\frac{11}{7}\)

\(\frac{69}{28}\) - \(\frac{11}{7}\) = \(\frac{25}{28}\)

= \(\frac{50}{56}\)
