If one of the lines of `m y^2+(1-m^2)x y-m x^2=0` is a bisector of the angle between the lines `x y=0` , then `m` is 3 (b) 2 (c) `-1/2` (d) `-1`

Options

A. 1
B. 2
C. `-1//2`
D. -1

Explanation

To solve the problem, we need to analyze the given equation and find the value of \( m \) such that one of the lines represented by the equation is a bisector of the angle between the lines \( x = 0 \) (y-axis) and \( y = 0 \) (x-axis).

### Step-by-Step Solution:

1. **Understand the Given Equation**:
The equation given is:
\[
m y^2 + (1 - m^2)xy - mx^2 = 0
