Under warabandi, how is each farmer's turn on a watercourse fixed?
C. A fixed time on a fixed day of a weekly cycle, in proportion to the farmer's landholding
Warabandi gives the whole outlet flow for a time proportional to area, at a fixed day and hour in a 7-day cycle. Application-based allotment is closer to Maharashtra's shejpali; equal hours ignores holding size.

Under warabandi on a 7-day cycle, how many hours does a farmer with 6 ha in a 120 ha outlet command receive, ignoring conveyance-time adjustments?
D. 8.4 hours
Turn = 168 h × 6/120 = 8.4 h. 1.2 h uses 24 h instead of 168 h; 7.0 assumes one hour per day; 20.0 divides 120 by 6.

Which measure reduces flood damage to a house without changing the flood itself?
A. Raising the plinth above the expected flood level
Flood proofing, such as raising plinths, protects property against a given flood. Detention, channel widening and levees all change the flood flow or level.

Under India's classification by culturable command area, a scheme with a CCA of 1,500 ha is
C. a minor irrigation project
India: minor below 2,000 ha CCA, medium 2,000–10,000 ha, major above 10,000 ha. Command area development is a programme, not a size class.

A tubewell yields 30 L/s and runs 10 h a day. Peak crop demand is 6 mm/day and application efficiency is 75%. What area can it serve at peak?
B. 13.5 ha
Daily volume = 0.030 × 36,000 = 1,080 m³; effective = 810 m³; area = 810 ÷ 0.006 = 135,000 m² = 13.5 ha. 18.0 ignores efficiency; 5.4 uses 4 h; 1.35 slips a decimal.

What is the function of the sluice in an irrigation tank?
B. To release controlled amounts of stored water to the command
The sluice is the controlled outlet to the command. Flood passing is the surplus weir; supply is the supply channel.

Which Indian state passed the Farmers' Management of Irrigation Systems Act in 1997, an early state law creating water users' associations?
B. Andhra Pradesh
Andhra Pradesh's 1997 Act created WUAs across its irrigation commands and was followed by other states' laws. The other states passed their own laws at different times.
