If identical bids are received,the buyer might choose to:

A) reject all bids.
B) initiate an investigation.
C) negotiate with one or more suppliers.
D) reject all bids and initiate an investigation.
E) reject all bids and negotiate with one or more suppliers.

If identical bids are received, it indicates a lack of differentiation among suppliers. Therefore, the buyer may choose to negotiate with one or more suppliers to gain additional value from the competition. Rejecting all bids or initiating an investigation may not necessarily address the issue of identical bids.
