KrS is the answer

Step-by-step explanation:

i'm not fully sure if it is the right answer so if u do know the real answer please tell me

Answer 2

The transfer of electrons is an ionic bond, therefore, we need to determine which substance includes an ionic bond.

CO2, is a covalent bond, which is the sharing of electrons, not transfer.
KBr, is an ionic bond, because (k) loses an electron to bromine.

So, our final answer is:- (3) KBr
