Answer:

The answer to your question is the letter B.

Step-by-step explanation:

Data

major axis = 16

minor axis = 10

Process

1.- Calculate the value of a

       major axis = 2a = 16

                              a = 16/2

                              a = 8

2.- Calculate the value of b

       minor axis =2b = 10

                              b = 10/2

                              b = 5

3.- Write the equation of a vertical ellipse

           [tex]\frac{(x - h)^{2}}{b^{2}} + \frac{(y - k)^{2}}{a^{2}} = 1[/tex]

 C = (0, 0) and h = 0, k= 0

4.- Write the equation of the ellipse

           [tex]\frac{x^{2}}{5^{2}} + \frac{y^{2}}{8^{2}} = 1[/tex]        

The right answer is B because the denominators are simplified.
