I feel like Projection is the answer, but I might confuse it with something else like Selection, which is for rows.

Union and Intersection are definitely for combining sets, but I can't recall if Projection is the exact term for selecting columns.

I'm a little unsure between the projection and intersection operations here. I know projection has something to do with selecting columns, but I can't quite remember the details. I'll have to review my notes before answering this.

The projection operation, that's the one I was thinking of. It lets you choose which attributes or columns you want to keep from a relation. I feel confident about this one.

Okay, I remember learning about the different relational algebra operations. I'm pretty sure the projection operation is the one that allows you to select specific columns from a relation. I'll mark that as my answer.

Hmm, I'm a bit confused on this one. Is it the projection operation that selects columns? Or maybe it's the union operation? I'll have to think this through carefully.
