How can bid-rigging manifest in procurement fraud?

• A. Competitors collude to fix bids, allocate contracts, or inflate prices.
• B. Independent bidding with transparent scoring.
• C. Bid-tampering by a single bidder without collusion.
• D. Early award of contract without bids.

Answer: (A)

Bid-rigging happens when suppliers coordinate instead of competing, manipulating the bidding process to control who wins and at what price. They may fix bids, allocate contracts among themselves, or inflate the winning price. That coordinated manipulation is exactly described here: competitors colluding to fix bids, allocate contracts, or inflate prices.

Other scenarios reflect different problems: independent bidding with transparent scoring promotes fair competition and is not bid-rigging; a single bidder tampering with a bid is fraud but not a collusive, multi-bidder scheme; awarding a contract early without bids bypasses the bidding process altogether, which is improper but not bid-rigging per se.
