Answer: D

The match is P-3, Q-1, R-4, S-2.

  • Cleaning of raw produce uses screening to separate stones, dust and foreign matter by size.
  • Grading sorts the produce into classes by overall quality: quality separation.
  • Size reduction by crushing or grinding is comminution.
  • Filtration removes suspended solids from a liquid: clarification.

The other options pair at least one operation with an unrelated process, such as cleaning with comminution.
