If $U_n$ $(n=1,2)$ denotes the $n^{\text{th}}$ derivative of $U(x) = \frac{Lx+M}{x^2-2Bx+C}$ (where $L, M, B, C$ are constants),then the equation $PU_2 + QU_1 + RU = 0$ holds for:

  • A
    $P=x^2-2B, Q=2x, R=3x$
  • B
    $P=x^2-2Bx+C, Q=4(x-B), R=2$
  • C
    $P=2x, Q=2B, R=2$
  • D
    $P=x^2, Q=x, R=3$
