Refer to the exhibit. Which command needs to be placed on the box where the code is missing to output the value of page_jd in the Python 3.7 script?
The correct answer is A. print(items.get('items')[0].get('page_id')). In the script, 'items' is a dictionary with a key 'items' whose value is a LIST (array) of objects. To access the first element of that list, you must use index [0] (or .get with index notation). Once you have the first list element (a dict), you then call .get('page_id') to…

Explanation
In the script, 'items' is a dictionary with a key 'items' whose value is a LIST (array) of objects. To access the first element of that list, you must use index [0] (or .get with index notation). Once you have the first list element (a dict), you then call .get('page_id') to retrieve its value. Option B is wrong because it treats 'items' as a nested dict instead of a list. Options C and D use direct bracket notation on a list without indexing, which would raise a TypeError.
