Direction: Each of the question consist of two statements, one labeled as the ‘Statement (I)’ and the other as ‘Statement (II)’. Examine these two statements carefully and select the answer to these items using the codes given below:

Statement (I): A channel in alluvium running with constant discharge and constant sediment charge will first from its flow section and then its final longintudinal slope.
Statement (II): If a channel in alluvium has a section too small for a given discharge and slope steeper than required, degradation and aggradation happen and then the flow section attains final regime.
