If the curve $y = ax^{2} + bx + c, x \in R,$ passes through the point $(1, 2)$ and the tangent line to this curve at the origin is $y = x$,then the possible values of $a, b, c$ are:

  • A
    $a = \frac{1}{2}, b = \frac{1}{2}, c = 1$
  • B
    $a = 1, b = 0, c = 1$
  • C
    $a = 1, b = 1, c = 0$
  • D
    $a = -1, b = 1, c = 1$
