The correct option is (d) Hollow concrete dam

The explanation is: Availability of construction materials sometimes dictates the choice. A buttress (hollow concrete dam) is a better choice if the material has to be transported from far off distances. If they are easily available it naturally calls for a concrete gravity dam.
