Parent channel means that type of canal which can share the water towards the sub canal.

Can anybody explain the answer in detail?

@M. Indravathi.

See when we take out a canal from a stream or river (parent channel) obviously we have to keep it at a lower level with respect to the parent channel so that water can easily enter into it. If we keep it at a higher elevation then proper entrance of water in the canal can not be achieved.

So, the given answer (B) is correct.
