class Score:
    def __init__(self, points):
        self.points = points
    def __lt__(self, other):
        return self.points < other
AMissing return statement
BMissing self parameter
CIncorrect method name __lt__
DComparing self.points to object, should be other.points
Step-by-Step Solution

    The method compares self.points to other directly, but other is expected to be an object.
  2. Step 2: Correct comparison

    It should compare self.points < other.points to access the attribute of the other object.
  3. Final Answer:

    Comparing self.points to object, should be other.points -> Option D
  4. Quick Check:

    Compare attributes, not objects directly [OK]
Quick Trick: Use other.attribute, not other alone in comparisons [OK]
