The line that correctly implements the requirement is B, because it uses "super" to call the getValue method from the parent class and then multiplies it by 2 to return twice the value of the parent. Option A would cause an infinite recursion because it recursively calls the same method without a base case. Option C has no reference to the parent class or its method. Option D uses "super" to reference a "number" variable, but there is no indication that this variable exists in the parent class or that it is related to the getValue method.
