It May Be Easy for Two Neighbors to Agree to Drain

It may be easy for two neighbors to agree to drain a meadow, which they possess in common, to grow crops. However, when the meadow is much larger and reaches thousands of people, the solution is more difficult because:

A) decision making is nearly impossible with so many people.
B) factions would form that would ultimately destroy the meadow for everyone.
C) the problem of the "tyranny of the majority" would be impossible to control.
D) the people involved would suffer from the "free rider problem."
E) the state of nature takes over, leading to conflict.
