The correct answer is:
Anteromedial and Posterolateral
They are named based on their tibial insertions.

You can remember the bundles of the ACL by the term "AMPLE"
-Anteromedial Posterolateral tightest in Extension

Of note the PCL has two bundles as well, and are commonly remembered by, "the PCL is your PAL"
-The PCL has an Anterolateral and posteromedial bundle

Use one of these mnemonics to keep them straight!
As the infamous Dr. Goljan once said, "Remember one and the other ones the other one."
