Why does json.dumps() with sort_keys=True sort keys inside nested dictionaries by default?

ABecause nested dictionaries are converted to strings before sorting.

BBecause sorting keys is disabled for nested dictionaries by default.

CBecause <code>sort_keys=True</code> sorts keys recursively at all levels of the dictionary.

DBecause <code>json.dumps()</code> cannot handle nested dictionaries.

Step-by-Step Solution

Solution:

Step 1: Understand sort_keys behavior
The sort_keys=True parameter sorts keys alphabetically at every dictionary level, including nested ones, during serialization.
Step 2: Differentiate from other options
A is incorrect; nested dicts are recursively processed. C is wrong; sorting applies to nested. D is false; nested dicts are fully supported. B correctly states recursive sorting.
Final Answer:
Because sort_keys=True sorts keys recursively at all levels of the dictionary. -> Option C
Quick Check:
sort_keys=True sorts keys recursively [OK]
