Solution

The correct option is A Aqueduct
Aqueduct -
  • In an aqueduct, the canal bed level is above the drainage bed level so a canal is to be constructed above the drainage.
  • The canal water level is referred to as full supply level (FSL) and drainage water level is referred to as high flood level (HFL).
  • The HFL is below the canal bed level.
  • Aqueduct is similar to a bridge, instead of roadway or railway, canal water is carried in the trough and below that the drainage water flows under gravity and possessing atmospheric pressure.
