Which would be the best closing sentence for a message to employees telling them that the company will no longer provide a free parking space for each employee in the company lot, but will instead issue a limited number of parking passes based on evidence of ride$-$sharing?

Question $15$ options:

Convenience is not an acceptable reason for continuing to contribute to pollution and traffic congestion on our roads.

Moving forward, we hope that you will take this opportunity to conserve fuel and contribute to a safer, cleaner environment by sharing transportation with your co$-$workers.

As of next Monday, you may not park in the free staff parking lot unless you are ride$-$sharing with at least one other employee.

If you have difficulties with or complaints about this new policy, please contact the Human Resources department.
