Which of the following results may you cause when moving off uphill you release the emergency brake lever too early in relation to releasing the clutch pedal?

Why?

If you release the handbrake before the clutch transmits enough driving force, the car may roll downhill. The brake no longer holds the car, while the drive cannot yet prevent rollback. Stalling or moving off abruptly mainly depends on clutch and accelerator control, rather than simply releasing the handbrake too early.
