The question asks: "You have $\frac{1}{5}$ of an apple. If you add $\frac{3}{5}$ of an apple, how much apple do you have?"

To find the total amount of apple, we add the two fractions:

Since the denominators are the same, we add the numerators:

The calculated answer is $\frac{4}{5}$. The provided options are:

b) $\frac{4}{8}$

c) $\frac{4}{4}$

d) $\frac{4}{7}$

e) $\frac{2}{7}$
The result $\frac{4}{5}$ is not among the given options.

Given that this is a multiple-choice question and the direct calculation does not match any option, we must assume there is a typo in the original question's denominator. Options b, c, and d all have a numerator of 4, which matches the sum of the numerators (1+3). If the original question intended the denominator to be 8 instead of 5, then the sum would be $\frac{4}{8}$. We will select option b based on this assumption.

The final answer is $\boxed{\text{b) } \frac{4}{8}}$.
