C) Projection, all the way! This is like the bread and butter of relational algebra. If you can't get this one right, you might as well throw in the towel.

Definitely C) Projection. I remember learning about this in my database class. It's the go-to operation for selecting attributes from a table.

I think the answer is C) Projection. This operation selects specific columns from a relation, which is exactly what the question is asking for.
