Amendments issued after the established deadline for proposals are sent to:

The correct answer emphasizes that amendments issued after the established deadline for proposals are sent to all offerors not eliminated from the competition. This approach ensures that all relevant parties who are still in contention for the contract are kept informed about any changes or updates that could affect their proposals.

Amendments to solicitations, including changes to terms or requirements, must be communicated to all offerors who are still eligible to compete. This process upholds the principles of fairness and transparency in the procurement process, allowing all offerors a chance to adjust their submissions based on the latest information provided. It's important that those offerors who are still considered for the award receive these updates so that they can make informed decisions moving forward.

The focus on maintaining competition and ensuring all parties have equal access to the most current information is a fundamental aspect of contracting procedures, thereby fostering an equitable and competitive environment.
