P. Ridge Canal	1. Aligned roughly at right angles to the contour of area, neither on a watershed nor valley, does not intercept any cross- drainage.
Q. Contour canal	2. Draw supplies from a river when there is high stage in river, not provided with head works for diversion of river water to canal.
R. Side slope canal	3. Aligned along a watershed, can com- mand areas on both banks of canal.
S. Inundation canal	4. Aligned nearly parallel to the contours of the area, irrigation possible on one side of the canal only.

Correct option is B

Solu – Ridge canal aligned along a watershed, can command areas on both banks of the canal.

 Contour canal aligned nearly parallel to the contours of the area, irrigation possible on one side of the canal only.

 Side slope canal is constructed at right angles to the contours & does not intercept
any cross drainage.

 Inundation Canal draw supplies from a river when there is a high stage in the river, not
provided with headworks for the diversion of river water to the canal.
