Answer 2

The statement is true. The dictionary key is immutable in nature.

• The dictionary itself is an abstract datatype.
• In this it contains a group of data with the different data types.
• And each data is stored as a key-value pair, that key is used to identify that data.
• We can add or replace values of the dictionary, it is mutable.
• But the key associated with the dictionary can't be changed.
• Therefore, the keys are immutable or unique.
