Respuesta :

B, they are different, I just took the test
The answer to this question would be: B.They are different. 

A compound will have different characteristics from their element. 
The interaction of different elements in a compound makes it so. They might have similar or opposite characteristic but it didn't always happen so those answers are not best.
