Ramona Has an Idea for an Electric Animal Brush That

Ramona has an idea for an electric animal brush that vacuums the animal hair and transforms it into usable sewing thread. Ramona calls her device the Hair-2-Thread and begins selling the device in January. Later that year, she decides the device would sell better if she had a patent, and she files the patent application in December. After finally receiving the patent the following year, Ramona discovers a similar device, the HairSew, is being sold by Saya and files a patent infringement lawsuit.
-Saya claims Ramona's patent is invalid because Ramona sold the product before filing her patent application. Is Saya correct?

A) Yes, because Ramona must file the patent application before offering the product for sale.
B) Yes, because Ramona must receive the patent before offering the product for sale.
C) Yes, because Ramona must file the patent application within six months of offering the product for sale.
D) No, because Ramona filed the patent application within a year after offering the product for sale.
E) No, because Ramona had two years to file the patent application after offering the product for sale.
