Martha secured a patent for a biomedical device she called "Gutmate." Believing that Deborah was a qualified manufacturer of biomedical devices, Martha sent Deborah the Gutmate plans and designs, together with a note: "I am prepared to hire you as manufacturer of Gutmate. I have little capital and propose, therefore, to convey to you a share of the patent ownership in exchange for your services. I invite your acceptance." Deborah responded, by writing: "Yes, we have a deal." Does Deborah's response constitute an acceptance?
A.Yes, because Deborah expressed her assent, clearly and unequivocally
B.Yes, because Martha explicitly invited Deborah to accept
C.No, because Martha's writing omits to describe Deborah as a qualified manufacturer
D.No, because Martha's writing proposes no definite bargain
E.No, because it did not present the word "accept" or "acceptance"
