Correct option is D
Statement:
Tonight, if I knead the dough, along with yeast and sugar, for my doughnuts, I will be able to bake and serve them fresh to my guest tomorrow evening.
Courses of Action:
(i) I must make arrangements to prevent the dough from getting spoilt and give good baking results. (True, since the dough is being prepared in advance, it needs proper storage (like refrigeration) to avoid spoiling).
(ii) I must cancel on my guest for tomorrow. (False, the statement does not suggest any reason to cancel the guest. In fact, the plan is to serve fresh doughnuts to the guest).
(iii) I must follow my doughnut recipe properly and bake them at the right temperature. (True, to get good results, following the recipe and baking correctly is necessary).
Both (i) and (iii) follows.
Thus, correct option is (d).
