Here’s the matching of what each level of the manorial system provided:
- Serf/Peasant - c. labor
- Lord - d. land, resources, and military support
- King - a. military aid and protection
- Knight/Vassal - b. food, shelter, and clothing
However, please note that the pairings can vary slightly based on interpretations. The most common understanding matches serfs with labor, lords with land and resources, knights with military aid and support, and kings with overall protection and command over the realm.
