Which exhibit displays a valid JSON file? A. B. C. D.

The correct answer is D. { "hostname": "edge_router_1", "interfaces": [ "GigabitEthernet1/1", "GigabitEthernet1/2", "GigabitEthernet1/3" ], }. Wait - the correct answer should actually be C, not D. Option C uses a proper JSON array (square brackets []) for the list of interfaces and has no trailing comma, making it fully valid JSON. Option D uses square brackets correctly but includes a trailing comma after the closing

Explanation

Wait - the correct answer should actually be C, not D. Option C uses a proper JSON array (square brackets []) for the list of interfaces and has no trailing comma, making it fully valid JSON. Option D uses square brackets correctly but includes a trailing comma after the closing bracket, which is invalid in JSON syntax. If the stated correct answer is D, this appears to be an error in the question key.
