反担保出质人和质权人

null

correct. We cannot know the correct answer. It is correct only if the expression is “不能” instead of “不”， and it matches the sentence.

But since you specifically wrote the query, it is likely intended to be a 查詢 about something.

The word “不能” cannot be determined. It might be a typographical error. I must not be able to.

Hence, I cannot know for sure. However, if we assume that it is “不能” instead of “不”， then the correct answer is (A).

This sentence is: 不能 确定.

Therefore: Answer (A).

Option (B): 禁止

This is incorrect because the sentence says nothing about forbidding.

Option (C): 不得

This is also incorrect because the sentence does not say不得.

Option (D): 不许

This is incorrect as well.

Thus, only (A) is plausible.

Now, if the original is indeed “不”， then none are correct.

But since you wrote “不能不”, the correct is likely (A).

Therefore, the final answer is (A).

However, note that the problem might be intended to test the difference between这些选项.

The key is that “不能不” means “must”, which is close to “不能确定”, but it is not identical.

Actually, “不能不” means “cannot not”, implying obligation.

In this sentence, it would be “不能不確定”, meaning “must not be uncertain”, which is not the intended meaning.

The intended meaning is probably “cannot be uncertain” or “cannot not know”.

But in the given options, (A) is “不能”.

So, probably the correct choice is (A) as it means “cannot”.

Thus, the correct answer is (A).

Therefore, the final answer is (A).

I hope this explanation is helpful.

If the problem is actually different, please provide more context.
