A.            \[\frac{1}{{{x}^{2}}}+\frac{1}{2{{y}^{2}}}=1\]                              
B.            \[\frac{1}{4{{x}^{2}}}+\frac{1}{2{{y}^{2}}}=1\]
C.            \[\frac{1}{2{{x}^{2}}}+\frac{1}{4{{y}^{2}}}=1\]                            
D.            \[\frac{1}{2{{x}^{2}}}+\frac{1}{{{y}^{2}}}=1\]
