答案：E

知识点：整除性估算

难度评级：660

解答：

所需瓶数为 $\dfrac{500}{35} = \dfrac{100}{7} = 14 \dfrac{2}{7}.$

因此最少必须购买 $15$ 个小瓶。

所以正确答案是 E。

The desired amount is $\dfrac{500}{35} = \dfrac{100}{7} = 14 \dfrac{2}{7}.$

This means that the smallest number of small bottles she must buy is $15.$

Thus, E is the correct answer.
