Плотность и объем скалярные величины, для их характеристики достаточно количества, направление не имеет значения.
Расстояние - тоже скалярная величина, неважно в каком направлении расстояние дано. Вот если бы было перемещение, то тогда нам нужно было бы указать и направление перемещения. А так, - скаляр. Сила, векторная величина, для ее характеристики нужно обязательно указывать величины силы (длина вектора) и направление силы.
Верный ответ - 3, или в) как должно быть в условии. В общем - векторная величина из списка только сила.
