The correct answer is option E.
If an irregularly shaped object (such as a wrench) is dropped from rest in a classroom and feels no air resistance, it will accelerate but will not spin.
In the absence of air resistance the object will accelerate but will not spin, it is because if there is no air resistance then same amount of force is applied on every part of the object. When all forces are same in all directions then it means net force is zero.
Moreover, the force is being applied in downward direction having same magnitude which leads to the fact that net force is zero.
Thus, the object will not spin as all forces cancel their effect. However, the object will accelerate due to force of gravity.
