How many AutoCAD objects are in a rectangle? 1) None 2) One 3) Four 4) Eight

It depends, if you draw a rectangle using four lines, you have four objects.

But if you draw a rectangle using the rectangle tool, you have one object.

Option 2 - There is only one Autocad object in a rectangle.

if you used polyline it has one object and if you use lines it has 4 objects.
