I think I saw a question like this in our last review session. I want to say it's option C, but I need to double-check my notes.

I’m a bit confused about the notation. Is AT just the transpose or does it involve something else?

I remember practicing a similar question where we had to identify the transpose. I feel like it might be option B, but I could be wrong.

I think AT refers to the transpose of the matrix, but I'm not entirely sure which option that would be.

I think I know how to do this. I'll start by writing out the given matrix, then compare each option to see which one matches the transpose.

Okay, I've got this! The transpose of a matrix just swaps the rows and columns, so I just need to visually compare the options to the given matrix.

This looks like a matrix transformation question. I'll need to carefully compare the given matrix to the options to determine which one is the transpose.
