How can a. be "none of the above" when there is nothing above it?

Acceleration for any object is 9.8 Meters/Second. So you would be safe in saying they will have the same acceleration. However, depending on how high they are dropped/thrown from, they could reach their terminal velocity, meaning the fastest possible speed with their given weight/drag, making "d" a posible answer.
But since there is minimal information provided, "b" is your best choice. All objects have the same gravitational acceleration.

D. simply by fact it does not say how severe the stone is thrown upward. If that's thrown 5 thoughts upward they unquestionably won't land on the comparable time and wouldn't have the comparable velocity.

b, providing neither of the stones falls from a distance sufficient to achieve terminal velocity.
