What are the advantages of an automatic anti-locking device (ABS)?

ABS prevents the wheels from locking up during hard braking by briefly reducing and reapplying brake pressure many times per second. The key advantage is that you keep steering control while braking hard. That’s why answer 1 is correct: with ABS you can brake firmly and still steer around an obstacle, because rolling wheels can transmit lateral (steering) forces, while locked wheels mostly just slide straight ahead.

The other statements are not advantages of ABS. Preventing wheelspin when setting off is the job of traction control (ASR/ESP), not ABS. And ABS does not “reduce the danger of tipping over” in bends; in a curve, ABS can help you keep the car steerable under braking, but it cannot override physics—if you enter too fast, the car can still understeer, oversteer, or in extreme cases roll depending on vehicle type and conditions.

Rule of thumb for similar questions: ABS helps you steer and maintain stability while braking, but it does not shorten stopping distance on every surface and it does not improve acceleration grip. You still must brake firmly and steer where you want to go.
