Refer to the exhibit. An engineer is comparing two files by using the unified diff format. Which cade snippet belongs to the new.py file? A. B. C. D.
The correct answer is A. 77 query_string_params = {'platformId': 'AIR-API141N-A-K9'}. In a unified diff, lines prefixed with + are present in the new.py file, indicating they were added or modified from the old.py file.

Why each option
In a unified diff, lines prefixed with `+` are present in the `new.py` file, indicating they were added or modified from the `old.py` file.
The line `query_string_params = {'platformId': 'AIR-API141N-A-K9'}` is preceded by a `+` in the unified diff exhibit. This `+` symbol signifies that this specific line is an addition or a modification present only in the `new.py` file.
The line `21 print(item['id'], item['hostname']` is not explicitly shown in the provided diff as either an added or unchanged line.
The line `24 print(item['id'], item['hostname'], item['managementIpAddress'])` is not explicitly shown in the provided diff as either an added or unchanged line.
While parts of this snippet are in `new.py`, the lines `query_string_params = {'hostname': 'CSBIKO-01.devnet.local'}` and subsequent lines are shown as both removed and re-added, which is less directly indicative of a unique addition compared to option A.
