Does a list using と end with が?

Question

Asking this other question has reminded me of another confusion I often have, one of my long standing bad habits that you'd think I'd have sorted after all this time in Japan.

I'm never quite sure how to end a list of two or more things. So, I want to say "I like apples and oranges."

Saying it this way seems weird, because of having と and が together. It just feels weird in my mouth.

りんごとオレンジとが好{す}きだ。

This next option also feels weird, though, because it's like saying, "apples and oranges and like".

りんごとオレンジと好{す}きだ。

Which is right? Or are both wrong?

Does it make a difference if there's more than two items?

りんごとオレンジとパパイヤと(が)好{す}きだ。

Answer 1

The most usual way is to attach と to all alternatives except for the last one:

りんごとオレンジが好きだ。
りんごとオレンジとパパイヤが好きだ。

(Unrelated note: “papaya” is usually パパイヤ rather than パパヤ in Japanese.)

Attaching と to all alternatives including the last one is acceptable.

りんごとオレンジとが好きだ。
りんごとオレンジとパパイヤとが好きだ。

I heard that in older days, と was always attached to all alternatives, but I do not have anything to back up this claim.

The following are ungrammatical.

りんごとオレンジと好きだ。
りんごとオレンジとパパイヤと好きだ。
