The correct option is (c) tank weir

For explanation I would say: To avoid overtopping of the tank bund in case of all dam reservoir projects, tanks are provided with arrangements for spilling the excess surplus water. These arrangements may be in the form of a surplus escape weir provided in the body or at one end of the tank bund. In the case of earth dam projects, some other arrangements like a siphon spillway can be provided.
