Answer 2

Spectator ions are the ions on the right side of the equation which do not combine to form products.
You have a typo in your formula (looks like a .jpg pic link you tried to paste), but we can see that potassium ions (K+) and bromine ions (Br-) appear unreacted on both sides of the equation. Therefore, the correct answer is C) K+ and Br-
Additionally, we know from solubility rules that Group 1 ions (including potassium, K, remain soluble in aqueous systems, meaning they do not combine with other ions and form products.
