Final answer:
Readers can infer that B) the bowl contains enough nuts to make the fruitcakes.
Step-by-step explanation:
Based on the sentence, "The buggy is empty, the bowl is brimful," readers can infer that the bowl contains enough nuts to make the fruitcakes.
The sentence describes a contrast between the empty buggy and the brimful bowl, suggesting that the task of filling the bowl has been completed.
Since the context mentions the ingredients for fruitcakes, it is logical to conclude that the bowl contains enough nuts to make them. Therefore, option B, "The bowl contains enough nuts to make the fruitcakes," is the correct inference.
