## Question

### Solution

Correct option is

We have,

Clearly, it represents a The Pair of Straight Lines passing through (1, 0). Since the bisectors of the angles between two lines are always perpendicular. So, the other bisector passes through (1, 0) and is perpendicular to 2x + y – 2 = 0. Hence, its equation is

.
