According to Article 12 of People's Opinions, an uncle is not a close relative, but a close relative in the General Principles of Civil Law. Therefore, according to the "general principles of the civil law" article sixteenth, paragraph 2, item 3:

(three) other close relatives and friends are willing to assume the responsibility of guardianship, with the consent of the unit where the minor's parents work or the residents' committee or villagers' committee of the minor's domicile.

"Willing to assume the responsibility of guardianship" in this law is inconsistent with the situation that uncle is unwilling to be the guardian of B. Therefore, because uncle C is not a close relative, he has no obligation to be a guardian under involuntary circumstances.

And A belongs to "② brothers and sisters;" Whether Party A is willing or not, Party A has the obligation to undertake the guardianship obligation without other guardians.

So the answer must be a, not C. If the standard answer that the landlord sees is C, then the standard answer is wrong, not me. Hehe, it's true. . . . . . . . This is a matter of jurisprudence and law, not guessing right or wrong. . . . . . . . Hmm. How interesting
