The parallelism condition for two straight lines,one of which is specified by the equation $ax + by + c = 0$ and the other being represented parametrically by $x = \alpha t + \beta$ and $y = \gamma t + \delta$,is given by:
- A$a\alpha - b\gamma = 0$
- B$a\gamma - b\alpha = 0$
- C$a\alpha + b\gamma = 0$
- D$a\gamma + b\alpha = 0$
