I'm using three questions in a list inside quotation marks, would I separate with a comma, semicolon, or nothing? Are the question marks even needed?

Question

A sentence with a list of questions inside quotation marks, how do I separate them? I can't find a solid answer anywhere.

Option 1: In simple terms, Naikan is based on three questions: “What have I received?” “What have I given?” and “What troubles and difficulties have I caused?”

Option 2: In simple terms, Naikan is based on three questions: “What have I received?”; “What have I given?”; and “What troubles and difficulties have I caused?”.

Option 3: In simple terms, Naikan is based on three questions: “What have I received?”, “What have I given?”, and “What troubles and difficulties have I caused?”.

Or would it be no question mark at all? In simple terms, Naikan is based on three questions: “What have I received”, “What have I given”, and “What troubles and difficulties have I caused."

The quotation marks have to be in it.

Answer 1

Not all the question marks are needed and famously, you wouldn’t start from there. Rather, you might ask “If I'm using three questions in a list inside quotation marks, would I separate them with a comma, semicolon, or nothing?”

Whichever applies, could you drop the initial phrase “In simple terms, Naikan is based on three questions: …”? It makes no difference.

The problem here is that instead of actually making a single list, you’ve tried to combine three individual items and keep them separate… which is almost as far from a list as you could get.

If they’re separate, treat them separately. If they really form a list, use one set of quotation marks.

“… What have I received? What have I given? What troubles and difficulties have I caused?”
