Plurals confusion.

Hello,

I found myself writing a sentence where I wasn't sure at all if or when I should be pluralising words in my sentence. Please can you respond with the grammatical logic for which of the below sentences is correct (if any). I'd like to know what this phenomenon is called, too. I'm also not looking to rewrite the sentence, more interested in the grammatical logic of this particular construction.

1. No matter what kinds of journey you make, we’ll be there.
2. No matter what kind of journeys you make, we’ll be there.
3. No matter what kind of journey you make, we’ll be there.

Which is correct? Thank you.
