If \frac{x}{m a}+\frac{y}{n b}=1 touches the ellipse {x^{2}}/{a^{2}}+{y^{2}}/{b^{2}}=1, then

Correct Answer is : m2=n2n2−1 or n2=m2m2−1

m^{2}={n^{2}}/{n^{2}-1} or n^{2}={m^{2}}/{m^{2}-1}

m^{2}={n^{2}}/{n^{2}+1} or n^{2}={m^{2}}/{m^{2}+1}

m^{2}={n^{2}+1}/{n^{2}} or n^{2}={m^{2}+1}/{m^{2}}

{m}^{2}={{n}^{2}-1}/{{n}^{2}} or {n}^{2}={{m}^{2}-1}/{{m}^{2}}
