Consider a circle with centre be .
So the equation of circle will be,
In the question it is given that the circle passes through .
Therefore, substituting and respectively in the equation we get,
So now putting the value of in the equation we get,
Now we will find intercept on line respectivley.
By substituting in the equation we get,
In the equation let be the roots.
So, from equation sum of the roots will be,
Product of the roots will be,
Now as we know that length of intercept is . So we will use the identity,
Substituting the values of equation and , we get
Hence the values of is or
By substituting the value of in the euqation we get,
In equation let be the roots,
Sum of the roots will be,
Product of the roots will be
Again using same identity we get,
Here the value of is or .
So now there are such sets of equation can be made by the sets of vales of which are
and .
For we will substitute in equation , we get
For we will substitue in equation , we get
For we will substitue in euqation , we get
For we will substitute in equation , we get
So only is matching with the given option.
