Answer: C
Explanation: It always goes away from the earth
The question states an accelerated motion of object along straight line, this implies a non zero force is acting in the object, which is increasing it's velocity and speed. However the direction of force is not given so it can't be determined that it is moving away from earth, hence correct answer is C.
