"If yes, which ones?"

Translation: Si oui, lesquelles ?

[duogm]

"si oui, lesquels" was also given right.

[Neolit1]

Why "si oui" isn't shortened to "s'oui" in this sentence?
There are 2 vowels one after another.

[relox84]

Si only contracts to s' before il and ils : si il -> s'il, si ils -> s'ils

[MichaelWood7]

More generally, I believe « si » would contract with any word starting with an "i," it's just that most of the time, that word is « il » / « ils. »
