Answer explanation

Match the concept to the correct structure:

• {"Malaysia": {"total_visited": 14}}

• Dictionary inside Dictionary

• {"France": "Paris"}

• Nested List in Dictionary

• {"Indonesia": ["Surabaya", "Bali"]}

To access "D" in this list , we use: nested_list[​ (a)   ][​ (b)   ]

When you want to store multiple values under a single key in a dictionary, you can use a ​ (a)   or another ​ (b)   .
