Identify the correct statement-

  • A
    If the algebraic sum of lengths of perpendiculars drawn from $(4,2)$,$(2,4)$,and the origin to a variable line is zero,then the line necessarily passes through $(2,2)$.
  • B
    If $P$ is a point inside $\Delta ABC$ such that $Ar(\Delta PAB) + Ar(\Delta PBC) + Ar(\Delta PAC) = Ar(\Delta ABC)$,then $P$ is the orthocenter of $\Delta ABC$.
  • C
    $A$ pair of lines always bisects the angle between the corresponding angle bisector pair.
  • D
    The harmonic conjugate of the midpoint of two points $A$ and $B$ is either of the points.
