The centers for disease control (CDC) is called in to investigate a coronavirus outbreak on the 2nd floor of an apartment building. The CDC investigator is thoroughly convinced that our patient zero responsible for starting the outbreak is on the second floor, but she interviews the 6 patients and their roommates to be sure of this. Based on the answers she received, she determined that each of the following people could have transmitted the virus to certain individuals as shown in the table below. 

A) Create a directed graph of the above information. Let C denote Carol, D denote Denielle, K denote Karen, M denote Madesha, S denote Sharicce, X denote Xiging. 

B) Suppose that there was a patient zero. Does the data support this supposition? If so, then identify the patient zero and explain your reasoning. If not, justify your answer.
