Acceleration is the change in velocity with respect to the time. The acceleration of the car at segment C is -30 meter per second squared. Hence the option B is the correct option.

<h3>Given information-</h3>

Segment A runs from 0 seconds 0 meters per second to 1 seconds 30 meters per second.

Segment B runs to 3 seconds 30 meters per second.

Segment C runs to 6 seconds 10 meters per second.

Segment D runs to 7 seconds 10 meters per second.

Segment E runs to 10 seconds 20 meters per second.

<h3>Acceleration</h3>

Acceleration is the change in velocity with respect to the time. Acceleration of a vector quantity which means it has both magnitude and the direction. It can be given as,

a=\dfrac{\Delta v}{\Delta t}

Here t denotes the time and v denotes the velocity of the body.

Acceleration at segment C,

a_c=\dfrac{10-40}{6-5}

a_c=-30

Thus the acceleration of the car at segment C is -30 meter per second squared. Hence the option B is the correct option.
