Answer 2

Answer:   (b) 3/5

Step-by-step explanation:

       16x^2 + 25y^2 = 400

Dividing whole equation by 400, we will get

       x^2/25 + y^2/16 = 1

Here, a^2 = 25   and    b^2 = 16

Eccentricity of ellipse = (1 - b^2 / a^2)^1/2

                                    = (1 - 16/25)^1/2

                                    = (9/25)^1/2

                                    = 3/5(ANSWER)
