Explanation:
> "The prices ____ are too high for us."

The sentence is referring to prices that were mentioned or provided, so we need a phrase that fits with prices being quoted or given.

Now, let's look at the options:

- A. you lent me — This refers to money that was borrowed, which doesn't fit the context of "prices." Incorrect.
- B. you quoted — This means the prices that were stated or mentioned. It fits perfectly in the context of the sentence. Correct.
- C. you attended — This is unrelated to prices. "Attended" is about going to an event, not about pricing. Incorrect.
- D. you gave me — While this could fit in certain contexts, it is less specific than "quoted" when referring to prices. Incorrect.
- E. you want to buy — This would refer to prices someone is interested in purchasing, but it doesn't fit with the sentence structure. Incorrect.
