A flush tank, attached to a toilet, has the shape of a right rectangular parallelepiped whose internal base dimensions are $2.5\,\mathrm{dm}$ and $1.5\,\mathrm{dm}$. In this tank there is a float that interrupts the supply when the height of the water column reaches 2 dm. Each time the flush is activated, all the volume of water contained in the tank is poured into the toilet. To reduce the volume of water poured each time the flush is activated, a person will place, inside this tank, 300 mL bottles filled with sand and capped, so that they remain submerged when the supply is interrupted. To guarantee efficient operation, the minimum amount of water poured each time the flush is activated should be 5 L. The maximum number of bottles that will be placed in this tank, guaranteeing efficient operation, is equal to (A) 10. (B) 8. (C) 4. (D) 3. (E) 2.
