Question

Based on the output below, which Python code shows the value of the "upTime" key? A. B. C. D.

Options

Ajson_data = response.json() print(json_data['response'][family]['upTime'])
Bjson_data = response.json() print(json_data['response'][0]['upTime'])
Cjson_data = json.loads(response.text) print(json_data['response'][family]['upTime'])
Djson_data = response.json() print(json_data['response'][0]['upTime'])

Explanation

Answer D is correct because when parsing a JSON API response using the requests library, response.json() is the proper method to deserialize the JSON payload into a Python dictionary. The 'response' key contains a list (array), so index [0] is used to access the first element, and then 'upTime' retrieves the specific key value - this is the standard pattern for navigating nested JSON structures from REST API responses.
