解答：

Étienne 的钱价值 $400\cdot1.30=520$ 美元，而 Diana 有 $500$ 美元。

Étienne 的钱的价值超过 Diana 的百分比为 $\frac{520-500}{500}\cdot100\%=4\%.$

因此正确答案是 B。

Étienne's money is worth $400\cdot1.30=520$ dollars, while Diana has $500$ dollars.

The percent by which Étienne's value exceeds Diana's is $\frac{520-500}{500}\cdot100\%=4\%.$

Thus, the correct answer is B.
