Question

Which is a cognate?
O überall
O Bruder
O Uhr
O Stuhl

Answer 1

i think it b hope this helps you

Answer 2

I think it's all of the above. But It could just be Bruder if you have to pick one.

Step-by-step explanation:

Cognates are two words from different languages that have a common origin/meaning/spelling. All of these German words are very similar to their english definitions.

If none of the above isn't an option then choose Bruder, because I know they have a similar origin.
