Drag and Drop

Hello Everyone,

I want to create a Drag and Drop with 

6 Drop Objects

6 Drag Objects

2 Correct Ans (Red & Green) but only one should be accepted

I have attached a screenshot for your reference. But only one answer should be accepted. For Example: If i drop the Red One correctly and click submit it should take me to other slide. If i drop the Green One correctly and click submit it should take to another slide.

Please help me how to do it, i am new to storyline variables.

Thanks in advance
