Chronic Fatigue Syndrome (CFS) Is a Debilitating Disease of Unknown

Chronic fatigue syndrome (CFS) is a debilitating disease of unknown etiology that is estimated to affect 17 million people worldwide. In a case-control observational study, researchers identified DNA from a human gamma-retrovirus (XMRV) in 68 of 101 patients with CFS (67%) compared with 8 of 218 healthy controls (3.7%) . We want to know if these data show evidence of a relationship between XMRV and CFS. Which of the following two-way tables represents the study findings correctly?

A)
$$\begin{array}{l}\begin{array} {| l| l | l| } \hline&\text {XMRV }&\text { no XMRV}\\\hline\text {CFS patients }&68&101\\\hline\text {Healthy controls }&8&218\\\hline\end{array}\end{array}$$
B)
$$\begin{array}{l}\begin{array} {| l| l | l| } \hline&\text {XMRV }&\text { no XMRV}\\\hline\text {CFS patients }&8&68\\\hline\text {Healthy controls }&101&218\\\hline\end{array}\end{array}$$
C)
$$\begin{array}{l}\begin{array} {| l| l | l| } \hline&\text {XMRV }&\text { no XMRV}\\\hline\text {CFS patients }&68&33\\\hline\text {Healthy controls }&8&210\\\hline\end{array}\end{array}$$
D) $$\begin{array}{l}\begin{array} {| l| l | l| } \hline&\text {XMRV }&\text { no XMRV}\\\hline\text {CFS patients }&76&319\\\hline\text {Healthy controls }&33&210\\\hline\end{array}\end{array}$$
