NSU organised a cricket tournament, but apart from the match itself, nothing was in order due to the fault of the food, carpet and trophy suppliers. NSU entered into a contract of sale of goods with Lexicon, a manufacturer of Trophy, to supply some Trophies for the NSU Cup Cricket Tournament. Lexicon agreed that they will supply trophies with their logo printed properly. However, due to their heavy workload, Lexicon appointed Pelicon, another renowned Company, to make the trophies within the deadline. Pelicon then asked NSU to visit the shop and examine the trophies before delivery, but NSU officials did not have any time to do so. While distributing them to the participants, one trophy just broke down on its own. It was quite embarrassing in front of the Chief Guest. After the distribution of the trophies, when the guests were having foods, it was found that the seller supplied Beef snacks, while NSU actually ordered chicken snacks, which was clearly stated in the receipt. Therefore, many guests having allergies to beef could not have them. Moreover, a few of the snacks contained small pieces of bones inside and one guest got injured while eating them. Besides, the carpeting which was procured by the NSU officials on sale or return basis to organise the closing ceremony was also stolen. NSU refused to take responsibility of such stealth and did not go for any legal action on the ground that they have not yet approved the sale and therefore the ownership has not yet been transferred to them.

Question: Identify the responsibilities of sellers of trophy, food and carpeting and also NSU as the buyer of those items in accordance with the Contract Act of 1872 and Sale of Goods Act of 1930.
