Answer:

Choice C is correct

Explanation:

Given the endpoints of the minor axis: (5,5) and (-1,5).
Vertices: (2,13) and (2,-3).


Standard form of ellipse is:

(x-h)^2/a^2 + (y-k)^2/b^2 =1

Minor axis length = 5 - - 1

minor axis = 6

b = 6/2

b = 3

b^2 = 9

Major axis length = 13 - - 3

major axis = 16

a = 16/2

a = 8

a^2 = 64

centre from vertices: midpoint formula

( 2 + 2) / 2 , (13 - 3) / 2

= (2, 5)

plug values in

(x - 2)^2 / 64 + (y - 5)^2 / 9 = 1

so our answer is C or the third choice
