Answer:

D.

Step-by-step explanation:

The difference in pizza delivered between driver A and driver B is 10 pizzas.

We can find this by doing 20-10 which is 10.

The MAD is 2.

D says that Driver A has less pizzas delivered than Driver B by 5 MADs. Since 1 MAD is 2, 5 MADs is 10.

Meaning D says that driver A delivered 10 less pizzas than Driver B, which is correct.

Hope this answer helped! :)
