2017 Season rewards ambiguous

Riot stated: " The Flex Queue allows up to five players to queue up and compete—a lot like 2016's Dynamic Queue—and those who climb in both will earn extra rewards at the end of the season. "

My question is by "both", which are you referring to ?

• Ranked Flex 5v5 & Ranked Flex 3v3
• Ranked Flex 5v5 & Ranked Solo/Duo ,
• any Ranked Flex & Ranked Solo/Duo.

Thanks.
