Two spheres A and B, where A has twice the mas of B, are projected at the same horizontal velocity off the edge of two different height shelves. Sphere A leaves from a height of 2.0 m. Sphere B leaves a shelf 1.0 m off the floor. If both spheres leave the edge if the table at the same instant, sphere A will land

Question

Two spheres A and B, where A has twice the mas of B, are projected at the same horizontal velocity off the edge of two different height shelves. Sphere A leaves from a height of 2.0 m. Sphere B leaves a shelf 1.0 m off the floor. If both spheres leave the edge if the table at the same instant, sphere A will land 
A at some point after sphere B
B at the same time as sphere B
C at some time after sphere B
D There is not enough information to decide
