Answer 1) the best options are phosphorylation and ubiquitination
removal of di sullphide bond will denature the protein eleminating any possible function so i dont think it should come under affecting protein function but i am not sure about this. I believe it should not be included, just the above mentioned 2 option should be correct.
Rest of your selected options are correct according to me.
