In order to compare two BowlingGame objects, we need to subtract the current object's score from the other object's score. This will give us a positive, negative or zero value, indicating whether the current object is greater than, less than or equal to the other object. Choice B correctly implements this logic by subtracting other.score from score. Choice A and C both contain errors in variable names and casting syntax. Choice D subtracts score from other.score, which will give us the opposite order to what we want in the comparison.
