If ` a^(2) + b^(2) = 25 ` and a focus of the ellipse
` (x^(2))/(a^(2) + 3) + (y^(2))/(b^(2) + 3) = 1` is `(sqrt(7) ,0)` , then equation of this ellipse is

A

`(x^(2))/(20) + (y^(2))/(13)=1`

B

`(x^(2))/(12) + (y^(2))/(19) = 1`

C

`(x^(2))/(19) + (y^(2))/(12) = 1`

D

`(x^(2))/(13) + (y^(2))/(20) = 1`
