c.

The correct answer is C.

A dune is defined as an accumulation of sand, created by the force of wind  combined with the flow of water which, in fact, has more or less the shape of a hill, although if one dune is compared to another there is diversity in the shape they can adopt (even tough both are hillish). Dunes are typically originated in desserts or in coasts and beaches and they keep on changing and moving constantly, as the combined action of wind and water keeps on accumulating sand.

it rather depends on the number of people voting in favor of the candidate.

this is an outcome of people's preferences.
