the answer is wrong, option b is correct answer.how(note 1 litre=1dm3=0.001 cubic meter.also first convert the given depth to meter. depth=volume/area so volume=depthxarea gives 3 cubic meter, convert to litre.i.e, 3/0.001=3000 litres

agree with #ziaullah. correct option is (b). 1 cubic meter= 1000 liters. now converting irrigation dept to meters we get (6cm=6/100=.06m). by multiplying area with depth (50*.o6) we got 3 cubic meter which is equal to 3000 liters
