one-to-one relationships

[Xixi Luo]

1. What are the correlations between A, B, and, C?
2. What are the pairwise correlations between A, B, and, C?
I intend to ask about one-to-one relationships of the three items.
Which one sounds more natural and clearer in a formal and academic context?

The first one makes sense (I think). However, the second one uses a phrase I have never seen before. Perhaps:

What is the relationship between A, B and C?

I had to look up "pairwise".

Thanks, I got it. The first one is better.
