A)                 \[\frac{1}{\eta }=\frac{1}{3\gamma }+\frac{1}{9K}\]

B)                             \[\frac{1}{K}=\frac{1}{3\gamma }+\frac{1}{9\eta }\]

C)                 \[\frac{1}{\gamma }=\frac{1}{3K}+\frac{1}{9\eta }\]

D)                             \[\frac{1}{\gamma }=\frac{1}{3\eta }+\frac{1}{9K}\]
