The correct answer among the choices provided is option C. The momentum of the car is 4620 g cm/s. To find the momentum, mass and velocity is multiplied with each other. Thirty grams multiplied by 154 cm/s is equal to the answer.

By definition, the momentum is given by:
 \(p = m * v\)
 Where,
 m: car mass
 v: speed of the car
 Substituting the values in the given definition we have:
 \(p = 30 * 154\)
 Making the corresponding calculation we have:
 \(p = 4620 g * cm / s\)
 Answer:
 the momentum of the car is:
 \(p = 4620 g * cm / s\)
