What is the maximum number of persons who may share a single Nobel Prize in one year?

The correct answer is B, three. The statutes of the Nobel Foundation allow a prize in one category to be divided among no more than three persons in a single year, and the money is shared between them. The rule is often discussed in the sciences, where large teams work on one discovery.

Option A, two, is the number of shares in many well known awards but not the limit here. Option C, four, is beyond what the statutes permit for individuals. Option D is wrong because a limit certainly exists, although the Peace Prize may be given to an organisation instead of a person, and the International Committee of the Red Cross has received it three times. Learn the neighbouring rule with it: since 1974 a prize may not be awarded posthumously, though a laureate who dies after the announcement still receives it.
