Choice "C" is correct. A purchaser has a right to inspect goods before paying for them unless the contract provides otherwise.
Choice "b" is incorrect. If the contract is silent, delivery is deemed to be due at the seller's place of business, or if the seller has none, at the seller's home. Thus, delivery here would be at Smith's home.
Choice "d" is incorrect. A seller must accept a check as payment or give the buyer additional time to obtain cash.
Choice "a" is incorrect. Unless otherwise agreed, payment and delivery are simultaneous conditions. Thus, payment here would be due on delivery.
