A Python script needs to produce a JSON string that is human-readable for debugging. The data is a list of dictionaries. Which json.dumps() call produces a nicely indented output?

json.dumps(data, sort_keys=True)

json.dumps(data, ensure_ascii=False)

json.dumps(data, separators=(',', ':'))

What does the ElementTree method ET.parse('data.xml') return?

The root element of the XML document

A string containing the XML content

A list of all elements in the document

An ElementTree object representing the parsed XML document

A Python dictionary contains a key 'data' whose value is a set of strings. When calling json.dumps() on this dictionary, what happens?

It converts the set to a list automatically.

It raises a TypeError because sets are not serializable by default.

It serializes the set as a JSON object with the strings as keys.

It ignores the set and serializes the rest of the dictionary.
