Answer:
The action by Grensfield State that is likely to receive the most support from the public is:
a. Coupling employee contribution plans with tax exemption benefits
Step-by-step explanation:
The employees of Grensfield State, including the public, would support pension contribution plans that are coupled with tax exemption benefits. The exemption benefits make contribution plans attractive to the workers. Engaging in any of the other three actions will not solve the pending problem nor win the support of the public to the state government's plans.
