A) " $\varOmega$ _luminous = 0.1, $\varOmega$ _matter = 0.3, $\varOmega$ _$\wedge$ = 0.7"
B) " $\varOmega$ _luminous = 0.02, $\varOmega$ _matter = 0.5, $\varOmega$ _$\wedge$ = 0.5"
C) " $\varOmega$ _luminous = 0, $\varOmega$ _matter = 0.1, $\varOmega$ _$\wedge$ = 0.9"
D) " $\varOmega$ _luminous = 0.02, $\varOmega$ _matter = 0.3, $\varOmega$ _$\wedge$ = 0.7"
