The correct option is (c) PVC water bars

The best I can explain: Metal water stops (both V-shape and Z-shape) and rubber water stops are used in ducts of aqueducts and super-passages in expansion joints. PVC water stops are generally adopted for Construction and contraction joints of aqueducts and super-passages.
