The correct option is- Soil and pebbles settle at the bottom of the beaker.
- Soil is partially soluble in water. But after two hours, the soil particles settle at the bottom of the beaker.
- Dried twigs and dead leaves are insoluble in water. But due to their light weight, they remain afloat in the water.
- Small pebbles are also insoluble in water but due to heavy weight, they settle at the bottom of the beaker.
