Hi, Neither is correct as written. The natural sentence would be: “If you refuse, I’ll be offended.” You don’t need “or” or “and” in this case — just a simple conditional sentence.

The natural option is: "If you refuse, I'll be offended." Avoid using "or" or "and" here.

Neither is natural or correct. 'And' and 'or' are used to connect two main clauses. Your sentences each have a main clause and a subordinate clause (the 'if' clause). You can't use these conjunctions here If you refuse, I'll be offended. Refuse, and I'll be offended - refusing will offend me Refuse, or I'll be offended - not refusing will offend me
