The correct order in the processing of wool is:
The correct order in the processing of wool is:
- A. Shearing-sorting-scouring - fiberspinning fiberdying - rolling
- B. Shearing-scouring-sorting - fiberspinning fiberdying - rolling
- C. Shearing - scouring - sorting - fiberdying fiberspinning - rolling
- D. Shearing-sorting - scouring - fiberspinning rolling - fiberdying
Step-by-step solution
The standard wool processing order is shearing, sorting, scouring, dyeing, spinning, and rolling. Option A is the only one with shearing-sorting-scouring in the correct order before the spinning and dyeing steps, even though the latter two are listed together. The other options either place scouring before sorting (B and C) or dyeing after rolling (D), which are incorrect.
