PLEASE HELP WHICH ONE IS CORRECT

The dot diagram represents the motion of the motorcycle as it moves from left to right

Students in an introductory physics lab are performing an experiment with a parallel-plate capacitor made of two circular aluminum plates, each 11 cm in diameter, separated by 1.0 cm. how much charge can be added to each of the plates before a spark jumps between the two plates? for such flat electrodes, assume that value of 3×106n/c of the field causes a spark.

If anyonee has done the momentum lab practical in physics can you give me the answers i am s lostt rnn : (
