If the zeros of the cubic polynomial $p(x) = ax^3 + bx^2 + cx + d$ $(a \neq 0, a, b, c, d \in R)$ are $\alpha, \beta,$ and $\gamma$,then $\alpha + \beta + \gamma = \ldots$

  • A
    $\frac{\text{coefficient of } x^2}{\text{coefficient of } x^3}$
  • B
    $-\frac{\text{coefficient of } x^2}{\text{coefficient of } x^3}$
  • C
    $\frac{\text{coefficient of } x}{\text{coefficient of } x^3}$
  • D
    $\frac{\text{coefficient of } x^3}{\text{coefficient of } x}$
