Correct option is (d) A siphon

Easy explanation: The bed of the natural drain 252.2 m is higher than the canal bed 248 by a margin of 4.2 m, the canal may be taken below the drain. The FSL of canal 253 m is above the drainage bed 252.2 m. the super-passage cannot be provided and the canal water has to be siphoned below the drainage.
