Answer: Option B 3-4i is the correct option

Step-by-step explanation:

we have formula for discriminant
D=b^(2)-4ac

after that we find the required variable that is to be find according to the quadratic equation given suppose we have to find x

then we have formula
x=\frac{-b\pm√(D)} {2a}

Here we have
\pm of roots if we have one root 3+41 other would be of opposite sign and hence,definitely be 3-4i.

Therefore Option B 3-4i is the correct option.
