vassal : corvee ::
  1. physician : appointment
  2. volunteer : service
  3. professor : instruction
  4. adjudicator : deliberation
Explanation
Answer: Choice (B) is correct.

Corvee is unpaid work performed by a vassal for a feudal lord. A physician does not conduct appointments that are unpaid, as a professor does not typically provide instruction without payment. An adjudicator, or judge, does not actually deliberate, so eliminate that choice. A volunteer offers to serve without pay, so that is the most appropriate choice.
