Correct answer - "Stack B, then Stack C, then Stack A" : All of the imports must be removed
before you can delete the exporting stack or modify the output value. In this case you must
delete either Stack B or Stack C, then you delete Stack A.
Incorrect:
"Stack A, then Stack B, then Stack C" - All of the imports must be removed before you can delete
the exporting stack or modify the output value. In this case you cannot delete Stack A first
because they are being referenced in the other Stacks
"Stack A, Stack C then Stack B" - All of the imports must be removed before you can delete the
exporting stack or modify the output value. In this case you cannot delete Stack A first because
they are being referenced in the other Stacks
"Stack C then Stack A then Stack B" - Stack C is fine but delete Stack B before Stack A
