Answer : Because the grass extends the time of the collision.

Explanation :

Denise is riding her bike and falls to the ground. During the collision, she hits both grass and cement.

He had fewer injuries to the area of her body that hit the grass because the grass extends the time of the collision and hence it imparts less impulse.

i.e. [tex]I=\dfrac{F}{t}[/tex]

Where

F is the force

t is the time of collision

Hence, the correct option is (d) " The grass extends the time of the collision ".
