An MS Chart question

Can somebody give me the answer to this 'simple' question?

In order to load chart data into an MS Chart from an array, what must be TRUE?
Choice 1
The array must be smaller than 32K.
Choice 2
The array must be a variant.
Choice 3
That cannot be done.
Choice 4
The array must contain only integers.
Choice 5
The array must be named DataGrid.

Preparing for a test? I'm going to have to go with choice #2 - the array must be a variant (You can find out about this by looking up the ChartData Property in VB Help)

I go for Choice 6
Don't use MS Chart
