A synergistic product line refers to a collection of products that work well together and complement each other. This means that the products do not hinder or contradict the effects of each other, but rather enhance their effectiveness when used together. This is different from having all products be biodegradable (A) or made from organic materials (C), as these characteristics do not necessarily have a direct impact on the compatibility of the products. Similarly, having the same fragrance (D) does not necessarily mean that the products are synergistic, as they may still have different functions or purposes.
