Python - Class Methods and Static Methods

Find the error in this code snippet:

class Animal:
    species = "Unknown"

    @classmethod
    def set_species(cls, species):
        species = species

The line 'species = species' assigns the parameter to itself, not to cls.species.
Step 2: Identify correct assignment
To update the class variable, it should be 'cls.species = species'.
Final Answer:
The assignment inside set_species does not update class variable -> Option C
Quick Check:

Quick Trick: Assign to cls.var to change class variables inside classmethods [OK]
