The question is asking to calculate the acceleration of the object if the velocity of an abject changes from 65 m/s to 98 m/s during a time interval of 12s, and base on my calculation, the possible answer would be letter A. 2.75 m/s. I hope you are satisfied with my answer and feel free to ask for more 

Answer

Find out the what is the acceleration of the object .

To prove

Formula

[tex]Acceleration = \frac{Final\ velocity - Intial\ velocity}{Time }[/tex]

Where

t = the time in which the change occurs

As given

If the velocity of an object changes from 65 m/s to 98 m/s during a time interval of 12 s .

Final velocity = 98 m/s  

Intial velocity = 65 m/s

Time = 12 s

Put in the formula

[tex]Acceleration = \frac{98 - 65}{12}[/tex]

[tex]Acceleration = \frac{33}{12}[/tex]

Acceleration = 2 .75 m/s ²

Option (A) is correct .
