When moving off, what will happen if the clutch pedal is released too suddenly?

What this question teaches

For the question "When moving off, what will happen if the clutch pedal is released too suddenly?", the correct answer is "Both" because this question is testing the correct use or direction of a vehicle control, so the right answer is the one that operates that control properly; the other choices such as "The vehicle will jump or surge forward." and "The engine will stop suddenly or vibrate violently." do not fit the rule as well.
