Business Undertaking is a term used to describe any activity or venture that is conducted for the purpose of making a profit. It can refer to a wide range of activities, from small businesses to large corporations. In this case, the term is being used in conjunction with the word 'TRIP, ' which suggests a journey or excursion taken for business purposes. This could include anything from a business TRIP to attend a conference or meeting, to a vacation taken for the purpose of networking and expanding one's business contacts.
