If the roots of the equation

\left(a^2+b^2\right) t^2-2(a c+b d) t+\left(c^2+d^2\right)=0

are equal, then

View answer and explanation

Correct option: D

a / b=c / d

Option D (

a/b = c/d

) is correct because the condition for equal roots leads to the equation

(ad-bc)^2 = 0

, which simplifies to

a/b = c/d
