ANSWER:

A.

[tex]\frac{1}{2}-0=\frac{1}{2}[/tex]

STEP-BY-STEP EXPLANATION:

We must subtract from the amount that Benjamin ate what his sister ate, like this:

[tex]\frac{3\cdot2}{5\cdot2}-\frac{1}{10}=\frac{6}{10}-\frac{1}{10}=\frac{5}{10}=\frac{1\cdot5}{2\cdot5}=\frac{1}{2}[/tex]

So that's the difference between both, the best way to represent then would be:

[tex]\frac{1}{2}-0=\frac{1}{2}[/tex]
