Bonjour
- le riz- le grain
- le poisson- la viande
- le sel
> CORRECT
-
le bifteck , la viande
les carottes, les légumes
(you used the definite article everywhere, so that's what I changed "les" carottes)
we usually say "les légumes"...
if you say "la carotte, le légume => ok
     OR   les carottes; les légumes => ok
le sel
I still don't understand why you write "le sel" and nothing else after
what is the purpose  of your exercise
