Option D                      

Explanation:

In simple words, Generic commercial product labels are differentiated by the exclusion of a brand name, often known only by product features and characterized by simple, typically colored-and-white labeling.

A generic product is also not generally aggressively advertised and often wipes the floor on a pricing comparison with other branded products. Most often, processed goods and medications are sold as generic items to consumers.
