If the sentence in the singular is:

> The butcher's and the hairdresser's are closed on Sunday.

What happens to the genitive if I want to make it plural?

1. >Butchers and hairdressers are closed on Sunday.
2. >Butchers' and hairdressers' are closed on Sunday.
3. >Butcher's shops and hairdresser's salons are closed on Sunday.
