The correct answer is D. 1821
Step-by-step explanation:
In the U.S. pharmacy, which is the field of creating and using medical drugs, was an important area since the colonial period because the plants found in the New World along with ideas from Native Americans provide new possibilities to create medicines and treat illnesses. This led to expeditions and multiple works to classify plants and their benefits as well as pharmacist arriving from Europe and creating "drugstores". Despite this, the first American pharmacy college was only created until 1821 as Pharmacist Ambrose Hunsberger and other apothecaries created the Philadelphia College of Pharmacy. Thus, the first American pharmacy college opened in 1821.
