Is this online marking correct? (economics h/w)

In case the image doesn't work:

Which of the following statements about the study of economics is false? Choose all that apply.

• Macroeconomics is the study of how an entire national economy performs.
• Microeconomics is the study of the economic behavior of individual economic decision makers.
• Economics is the science that deals with the allocation of limited resources to satisfy unlimited human wants.

Now it is my opinion that all 3x statements are true, thus, not false. Therefore I have submitted an answer with 0x tickboxes filled.

Having exhausted my 3rd attempt playing around the answer box reveals that all 3x should be ticked, labelling all as false.

Am I having a blond moment or is this marking ridiculous

Could say that Macroeconomics is the study of economics at an aggregate level that may be higher than national level.

similarly microeconomics deals with small subsets of the economy not necessarily an individual decision maker.

I would say that three describes the theories of supply and demand

but some of the things above are splitting hairs...

All three to my knowledge (in a general sense) are indeed correct, especially number three. In fact, in my first economics lesson the first thing we were taught was the "limited resources, unlimited wants".
