When designing an accessor method like getName in Python, we want to return the value stored in the instance attribute that holds the name.
Option A: 'return self' would return the entire object instance, not the name string, which does not satisfy the purpose of an accessor that should provide the pet's name.
Option B: 'return self._name' directly returns the value of the private attribute _name, which is exactly the intended behavior for getName in this class.
Option C: 'return' is incomplete syntax; a return statement must specify what to return, otherwise it will cause a syntax error or return None depending on context, and it does not access any attribute.
Option D: 'return _name' would attempt to return a variable named _name from the local or global scope, but since the attribute is stored as self._name on the instance, this name is not defined in the local scope, leading to a NameError.
Thus, options A, C, and D fail to correctly implement the accessor, while option B correctly returns the pet's name stored in the instance attribute.
