Let $A(5, -3)$,$B(3, -2)$,and $C(-1, 5)$ be three points. If $P$ is a point satisfying the condition $PA^2 + 2PB^2 = 3PC^2$,then a point that lies on the locus of $P$ is

  • A
    $\left(-\frac{1}{7}, \frac{1}{2}\right)$
  • B
    $\left(-\frac{5}{2}, -2\right)$
  • C
    $\left(-\frac{2}{21}, \frac{31}{66}\right)$
  • D
    $\left(2, \frac{37}{22}\right)$
