Protocells are self-organized, spherical collection of lipids. This is the proposed as the stepping stone to the origin life. One of the important qualities of protocells is its self-replicating, using the amphiphilic molecules. This requires repeatable set of chemical events.
Answer:
Substrate. The substrate is the surface on which the river organisms live. It may be inorganic, consisting of geological material from the catchment area such as boulders, pebbles, gravel, sand or silt, or it may be organic, including fine particles, leaves, wood, moss and plants.

The best answer would be option 3:
Fault Q occurred before layer K was deposited.
If you'd like to know why:
As you can see in the diagram, fault Q does not cross layer K. It stops right under it, so this means that the fault occurred first, then over a span of time, layer K was deposited.
To rule out the rest:
The oldest layer is the one at the bottom so that should be Layer B.
The youngest should be the top-most layer, unless a fault or an intrusion cuts through it, so Layer K is the youngest.
The last option is wrong because fault Q cuts through all those layers, which means it happened after those layers were formed.
