Sorry, my answer is "Anonymous" as your post is Anonymous. There is no need for an Anonymous question in this category, Most 'Anonymous' posts are trolls, maybe yours is not, but the high likelihood is there. If you post as yourself, I would be glad to help you with any problem you have.
I spend a lot of time on each problem, I just want to make sure it's for a worthwhile cause.

Salt bridge serves two main functions:
(i) It completes the circuit by allowing ions carrying charge to move from one half cell to the other.
(ii) It provides cations and anions which replace those consumed at the electrodes or which balance the charges on any ions formed from the electrode.
Therefore, salt bridge must be made of a strong electrolyte. Among the options, NaCl, KI and KCl are strong electrolytes, but CH₃COOH is a weak electrolyte.
The answer: CH₃COOH
