Option (C) is correct.
In the dictionary, there are no index values.
About Dictionary Vs Index value :
- A dictionary is a Python container that keeps unsorted and changeable mappings of unique keys to values.
- Dictionary entries are written with curly brackets (), which include key-value pairs separated by commas (,). A colon separates each key from its value (:).
- In the dictionary, there are no index values. The dictionary is a comma-separated collection of key: value pairs enclosed in curly brackets. Dictionaries are optimized to retrieve values once the key is known.
