View answer and explanation

Correct option: B

(\pm 2 / 5, \pm 1 / 5)

Option D (

\left(\pm \frac{2}{5}, \mp \frac{1}{5}\right)

) is correct because using the formula for points on the ellipse where tangents have a given slope, we find the points to be

\left(\pm \frac{2}{5}, \mp \frac{1}{5}\right)
