A particle starts from origin O from rest and moves with a uniform acceleration along the positive x-axis.

Hi, I have a question and I hope anyone could answer it:

A particle starts from origin O from rest and moves with a uniform acceleration along the positive x-axis. Identify all figures that correctly represent the motion qualitatively. (a = acceleration, v = velocity, x = displacement, t = time)
