Can an expert out there clarify for me what Cisco classifies as a "baby giant"? Frame size (MTU) of 1500, 1518, or 1600?

Cisco classifies a "baby giant" frame of having an MTU above the 1500bytes or 1518bytes but less than 1600bytes, depending on how your switch is setup for default MTU size. Above the 1600bytes (<9216bytes), they are considered "jumbo" frames.

Hmm, tricky fish. So if I ran into a question like this and my assumption was that the switch is configured in it's default state of an MTU of 1500 (which I understand is really 1518 with some overhead), I know that 9216 is a Jumbo Frame (Normally used for SAN/iSCSI), but the only other answer that would make sense is 1600? I don't see a 1599 option that seems to match the "between 1518 and 1600 spec... Would you answer a question like this as 1600?
Which MTU size can cause a baby giant error?
A. 1500
B. 9216
C. 1600
D. 1518 -
I would say that according to cisco documentation two things would have to happen here to understand it: One, you would need to know how to discover the currently set MTU size on your device. Two, is this the default MTU size for that device.
If the default is 1500, then `>1500 but less than 1601 ( I put the 1601) would be a baby giant.
If the default is 1518, then >1519 but less 1601 would be the baby giant.
