"I am making an onion and carrot soup."

Translation: Robię zupę z cebulą i marchewką.

Native polish here. Given sentence would rather translate to: "Robię zupę cebulową i marchwiową".
"Robię zupę z cebulą i marchewką" should be: "I am making a soup with onion and carrot".
with = z, and "with" is missing in the English sentence.

I don't understand why both 2 and 3 are correct? Two different forms of carrot?

Unfortunatelly, we don't know what "2" and "3" mean.

[Miknairb]

Choice 2 uses 'marchewka' and choice 3 uses 'marchwia' and apparently both are correct forms for carrot. I am sorry I don't have the ability of writing 'a' with a little tail.

[mihxal]

".marchewka" and marchew" are two forms of the same word and both are in common use

Thank you for your reply.

It's called ogonek (which does indeed mean tail).
