"or" in the interrogative sentence

[Pavel Bond]

I can't find information how to say "or" in an interrogative sentence.
In the affirmative it is А 또는 В, А나 В.
But in the interrogative?
For example: Is it a pen or a pencil?
Are you working or sleeping?
Is it your pen or your mother's?
Do you like apples or pears?

 

[Nokdu23]

Well. In these cases, "or" is used as "아니면"

Is it a pen or a pencil? ->펜 아니면 볼펜인가요?
Are you working or sleeping?->일하거나 아니면 자고 있으신가요?
Is it your pen or your mother's? ->당신 볼펜인가요 아니면 당신의 부모님 것인가요?
Do you like apples or pears?-> 사과 좋아하시나요 아니면 배 좋아하시나요?
