Thank you for the opportunity to help you with your question!

OPTION D )  0.8 m/s^2


acceleration from 5 s to 10 s

at 5s , velocity is 3.0m / s^2

at 10s , velocity is 7.0m / s^2

change in velocity = 7 - 3 = 4 m / s^2

time taken = 10 -5 = 5 sec


acceleration =  change in velocity / time taken

                     =   4 / 5

                    = 0.8 m/s^2....................................................ANSWER
