**(c)**

If the point of intersection of two lines with coordinate axes be concylic, then product of intercepts on -axis is equal to product of intercepts on -axis by these lines. This is a geometric property. The intercepts on -axis are and and whose product is . Also, the intercepts on -axis are , and , whose product is also . Hence, the four points are concylic
