D. Missing Null Check
Wasn’t sure on why this was the answer but after looking at what this answer meant, by seeing what the object blue =null; string could potentially mean, is that since this string is there, it is forcing the object blue to equal null, therefore, the official null check has become that ‘object blue’ rather instead its own string for a null check. the Object Blue potentially means something else but is equaling null in this case, and there is no further mention of null in any other script, therefore my answer lead to the logic of D. Missing Null Check, which was the correct answer.
