B, reservoirs.

Dams are used to conserve water and to convert it into hydroelectric energy.

Aqueducts are used to move water from one source to another, think sort of like irrigation.

Valleys are plains of grass, has nothing to do with water.

Reservoirs however, are used to <u>reserve</u> water, <u>Reserve</u>oirs.
