Wow, these questions really separate the JSON pros from the JSON posers. I'm just glad I'm not the one who wrote 'boros' instead of 'boroughs' in B).

I think A), B), and D) are valid JSON, but C) is a bit of a mess. Semicolons instead of colons? What is this, the Stone Age?

Haha, looks like Cory is having trouble with their JSON syntax. Commas and colons are key, my friend!

B) and C) have some issues. B) is missing commas between the key-value pairs, and C) has semicolons instead of colons between the keys and values.

A) and D) are valid JSON documents. The keys and values are properly formatted, and the empty object in D) is also a valid JSON document.
