✔ 最佳答案

答案應該係B

A唔岩
因為如果市場係複雜的話，應該會被其他較簡單既機制取代
因為咁複雜既話，Transaction cost都會非常之高
而市場就係一個有較減低Transaction cost既機制

B岩
因為假設所有人都係極大化既
咁多人都用市場交易，即係市場令佢地"賺"得最多
係另一方面睇，因為市場只用價格競爭，唔會出現租值消散
而且，跟據高斯定律，資源最終會透過市場交易去到最efficient既

C唔岩
因為consumer's surplus唔一定出現，有機會被賣方extract
但係消費者就算冇consumer's surplus都仍然會使用市場交易

D唔岩
因為用market transaction都唔代表owners and managers一定賺
仍然要睇返生產成本，所以呢個唔係用market既原因
