In the question below, three sentences are given

Solution

A states a fact about lunch being the biggest meal of the day; B gives a complementary fact and gives more information about the courses included in lunch. AND will be used here to join the two sentences. C tells us a contrasting fact about dinner being lighter in comparison to lunch. WHILE or WHEREAS can be used as a link here. 2 and 3 & 2 and 4 can be used as possible connectors, out of which only the latter is given in the options. The joined sentence will be: "Lunch is the biggest meal of the day and it often includes three or four courses plus dessert, whereas inner is much lighter and eaten around ten at night." Thus, (e) is the right answer.
