Answer: d. Review and renew.
Explanation: The nonprofit lifecycle is given as the process by which firms pass through growth and decline as a result of changes in systems, processes and elements that support the firm's existence.
Firms are established, then they grow and develop, and eventually reach maturity, after which they begin to decline, and finally, in many cases, they die.
Farmers Animal Farm is at the "review and renew" stage. This is a stage that immediately follows maturity, wherein questions are asked on how to ensure sustainability and if there is, how can the organisation renew and move forward. The transition calls for new policies and procedures to be followed, more upgrades to be attained, development, and more.
However, if these are not achievable, then there is a possibility of decline and termination of the organisation.
