What am I missing in this 215 exam question?

Hi. I am studying for the 215 exam. My training provider has mock exams based on the material for this exam that enable me to move on to the next stage of study, which is the MS 215 exam. There is one question that is giving me problems -- the answer seems too easy.

QUESTION: You are planning to install Windows 2000 server on a computer that has five 20-GB hard disks. The disks are completely blank; no operating system has ever been installed on any of them, LBA is supported. You want to use Windows 2000 setup to create a volume as large as possible and to place the system and boot partitions on that volume. Which is the most accurate estimate of the maximum size of the volume that you are going to create? POSSIBLE ANSWERS:
A 2 GB
B 4 GB
C 8 GB
D 16 GB
E 20 GB
F 100 GB

F was my choice, as during Windows setup, the system detects all mass storage and you can choose from using all space or a percentage of space. As I said, it seems to easy. Can you please correct me if I am wrong and explain to me why? Also, what is LBA and what does it do? Thanks in advance.

LBA stands for Logical Block Addressing. It is used to allow larger than 8 GB hard drives to be used on ATA IDE. Combining all five drives into a single volume provides for the largest storage capacity. The key to this question is to avoid assuming you need fault tolerance via a higher-level RAID configuration.
