[tex]\frac{1}{2}=\frac{1 \times 2}{2 \times 2}=\frac{2}{4} \\ \frac{3}{4} \\ 2<3 \Rightarrow \frac{2}{4} < \frac{3}{4} \Rightarrow \frac{1}{2}<\frac{3}{4} \\ not \ greater \\ \\ \frac{2}{5}=\frac{2 \times 4}{5 \times 4}=\frac{8}{20} \\ \frac{3}{4}=\frac{3 \times 5}{4 \times 5}=\frac{15}{20} \\ 8<15 \Rightarrow \frac{8}{20} < \frac{15}{20} \Rightarrow \frac{2}{5} < \frac{3}{4} \\ not \ greater[/tex]

[tex]\frac{5}{8} \\ \frac{3}{4}=\frac{3 \times 2}{4 \times 2}=\frac{6}{8} \\ 5<6 \Rightarrow \frac{5}{8} < \frac{6}{8} \Rightarrow \frac{5}{8} < \frac{3}{4} \\ not \ greater \\ \\ \frac{7}{8} \\ \frac{3}{4}=\frac{3 \times 2}{4 \times 2}=\frac{6}{8} \\ 7>6 \Rightarrow \frac{7}{8} > \frac{6}{8} \Rightarrow \frac{7}{8} > \frac{3}{4} \\ greater[/tex]

The answer is D. 7/8.
