The correct answer is: A. aqueduct and syphon aqueduct.
An aqueduct is a bridge that carries water across a valley or other low-lying area. A syphon aqueduct is a type of aqueduct that uses a syphon to carry water over a high point. A syphon is a pipe that is bent in such a way that the water flows from one end to the other without having to rise above the level of the outlet.
In the case of the drainage water intercepting the canal, the aqueduct and syphon aqueduct can be used to pass the canal below the drainage. The aqueduct will carry the canal over the drainage, and the syphon will carry the water from the canal to the other side of the drainage.
The other options are incorrect because they do not provide a way to pass the canal below the drainage. Option B, aqueduct and super passage, is incorrect because a super passage is a bridge that carries a road or railway across a canal. Option C, super passage and canal syphon, is incorrect because a canal syphon is a type of syphon that is used to carry water across a canal. Option D, level crossing, is incorrect because a level crossing is a place where a road and a railway cross at the same level.
