Q3

​Q3. Let coordinates of the points A and B are (5, 0) and (0,7) respectively P and Q are the variable points lying on the x  and y -axis respectively so that PQ is always perpendicular to the AB. Then locus of the point of intersection of BP and AQ is


    (A) x ² + y ² – 5x + 7y = 0                              (B) x ² + y ² +5x – 7y = 0 


    (C)​ x ² + y ² – 5x + 7y = 0                               (D) ​x ² + y ² – 5x – 7y = 0
