Who receives amendments issued after the established time of proposal receipt?

The correct answer pertains specifically to all offerors that have not been eliminated from the competition. After the established time for proposal receipt, any amendments to the solicitation are intended to reach only those parties who still have an active interest in submitting a proposal. This means that if any offeror has been eliminated from consideration, they no longer receive updates or amendments that could potentially impact their proposal.

This focused dissemination ensures that the integrity of the competitive process is maintained, allowing only viable candidates the opportunity to be informed of any changes that could affect their bidding strategy or response. Therefore, the amendments serve to provide essential information to those who remain contenders for the contract, aligning with the principles of fair competition and transparency in contracting.

The other options do not fully capture this specificity. For instance, while all parties receiving the original solicitation may initially be sent amendments, those who are no longer in the competition do not require further correspondence regarding changes. Likewise, the term "only eligible bidders" is somewhat vague, as eligibility can encompass different criteria; therefore, the answer that focuses on those not eliminated from competition is more precise. Lastly, contract performance agencies are typically involved in the execution phase and do not directly receive proposal amendments during the bidding process.
