Auction or dynamic-pricing market is an example of ________.
- (a)B2B Commerce
- (b)C2B Commerce
- (c)C2C Commerce
- (d)None of these
Correct — A (B2B Commerce) or C (C2C Commerce), both accepted. Auction/dynamic-pricing structures appear genuinely in both models: in B2B, businesses use online procurement/industrial exchanges where prices are set through bidding or reverse auctions between businesses; in C2C, individual consumers trade directly with each other through auction marketplaces (the classic example being eBay-style peer-to-peer auction sites) where price is set by bidding rather than a fixed tag. Because auction/dynamic pricing is a real feature of both models, MPPSC's key credited both A and C.
- (b)C2B Commerce — C2B is where an individual consumer initiates a transaction toward a business (e.g., offering to sell a service, or naming a price for a business to accept/reject) — its defining feature is who initiates the deal, not an open auction/bidding mechanism.
- (d)None of these — Wrong — auction/dynamic-pricing markets are a well-established feature of both B2B exchanges and C2C marketplaces, so this option is incorrect.
E-commerce transactions are classified by who is buying and who is selling: B2B (business-to-business), B2C (business-to-consumer), C2B (consumer-to-business) and C2C (consumer-to-consumer). Pricing mechanism is a separate axis from this classification — a fixed-price catalogue and an auction/dynamic-pricing market can both exist within the same B2B or C2C category. Auction/dynamic pricing simply means the price is discovered through bidding or real-time supply-demand adjustment rather than being fixed by the seller in advance.
The trap in this question is assuming 'auction' maps to only one model. In practice, MPPSC's key recognises that auction/dynamic pricing genuinely occurs in peer-to-peer consumer auctions (C2C) as well as business procurement exchanges (B2B) — so a student who only remembers the eBay-style C2C example misses half the accepted answer.
- B2B, B2C, C2B, C2C — the four standard e-commerce models, classified by buyer/seller type
- Auction/dynamic pricing is a pricing mechanism, not itself one of the four models
- C2C auction example: peer-to-peer consumer auction marketplaces
- B2B auction example: online industrial/procurement exchanges using competitive bidding
MPPSC's key credited both B2B and C2C, since genuine auction/dynamic-pricing markets exist in each.
- Assuming 'auction' belongs only to C2C (eBay-style) and forgetting B2B procurement exchanges also use bidding
- Confusing C2B (consumer names the price to a business) with C2C or B2B auction mechanisms
MPPSC/UPSC test e-commerce models either by asking to classify a described scenario (as here) or by asking for a real-world example of a given model (e.g., Q30 in this same paper, on C2B).
