If a point P moves such that the sum of the squares of its distances from two fixed points A and B is a constant, then the locus of the point P is

A straight line

A circle

Perpendicular bisector of AB

An arbitrary curve

The locus is a circle.
Standard equation of circle is
(x - a)² + (x - b)² = r²
where(a,b) is the centre and r is the radius of circle.
