The correct answer is 'D', all of the above is possible. The bed of an alluvial channel along the flow can take on different forms depending on the specific conditions of the channel and the flow. For example, in a stable channel with a relatively low sediment load, the bed may be relatively flat. However, in a channel with a high sediment load or with high velocity flow, the bed may be rippled or even duned. Additionally, in meandering channels, the bed may be way. The bed morphology of an alluvial channel is a constantly changing and influenced by many factors such as sediment load, discharge, channel slope, and channel width.

Alluvial channels are formed by the deposition of sediment carried by water. The bed of an alluvial channel along the flow is not always flat, way or duned and rippled. It can be any of the following:
1. Flat: The bed of an alluvial channel can be flat if the flow of water is slow and the sediment load is heavy. In such situations, the sediment settles down quickly and forms a flat bed.
2. Way: The bed of an alluvial channel can be way if the flow of water is moderate and the sediment load is moderate. In such situations, the sediment settles down in a linear pattern and forms a way.
3. Duned and Rippled: The bed of an alluvial channel can be duned and rippled if the flow of water is fast and the sediment load is light. In such situations, the water flows over the sediment and forms dunes and ripples.
4. Possible: In some cases, the bed of an alluvial channel can be a combination of the above-mentioned types. It is possible that the bed may be flat in some sections, way in other sections, and duned and rippled in some other sections.
Hence, it can be concluded that the bed of an alluvial channel along the flow can be flat, way, duned and rippled, or a combination of these types.
