  The differential equation corresponding to the family of parabolas whose axis is along $x = 1$ is
  Identify the correct option from the following:

  • $\frac{d^2 y}{dx^2} - (x - 1) \frac{dy}{dx} = 0$
  • $(x - 1) \frac{d^2 y}{dx^2} - \frac{dy}{dx} = 0$
  • $(x - 1) \left( \frac{d^2 y}{dx^2} \right) \frac{dy}{dx} - y = 0$
  • $(x - 1) \frac{d^2 y}{dx^2} - dy - y = 0$
