Answer 1

The correct option is C Statement 1 and 2 are correct, and statement 2 is the correct explanation for statement 1

While we tend to remain at rest with respect to the seat until the driver applies a braking force to stop the car. With the application of brakes, the car slows down, but the upper part of our body tends to continue in the same state of motion because of its inertia and will move forward, and may lead to accidents.
