Technical B is correct. Low unsprung weight makes the vehicle handle better on irregular surface.

Explanation: Unsprung weight are those weight that are not carried by the spring in a vehicle. The unsprung weight are carried by the wheels and tires of the vehicle.

Sprung weight are those weight carried by the spring of the vehicle.

In an irregular surface, a car that it's Unsprung weight is less will be more easier to control, because the tires and wheels which are controlled by the vehicle handle are lighter. Much weight is not on the wheels and tires, so it will be easier to control the tires of the car, when moving on an irregular surface. Example is, controlling an SUV car which almost all the weight are sprung, and controlling a petroleum tanker which has high Unsprung weight. The car handle of this vehicle differs very much in terms of lightness and easiness to control. The SUV will be more easier to control.

Technical A is wrong, because the wheels and tires are unsprung weight, sprung weight are those weight carried by the spring of the car
