Right option is (a) True

Easiest explanation: The canal alignment may be changed so that the crossing is shifted to the d/s where drainage bed is low if the conditions are not suitable for the construction of a siphon-aqueduct. Thus, sufficient headway becomes available for constructing an aqueduct. The CD works are finalized before the canal alignment.
