An ionic bond is expected between K and Br.
Ionic bond
The correct answer would be a polar covalent bond.
As the electronegativity difference between silicon and bromine is less than 1.7, a polar covalent bond is formed between silicon and bromine.
polar covalent
electron- sharing.
Covalent
Ionic bonding
In science, I refrain from making absolute statements. My research has not revealed that copper has a bonding configuration other than metallic. So, I would say one kind of bonding for now. Others can correct me.
Non metals generally form anions. They gain electrons during ionic bonding.

The bonding is covalent.
