Final answer:
The correct pair of words is 'c) Wrangling, Precluding' as they are both presented together in the question. 'Wrangling' means to argue noisily, and 'Precluding' means to prevent, with no evidence suggesting to choose only one.
Step-by-step explanation:
The correct pair of words from Problem #12 is c) Wrangling, Precluding. The reason for this is that in the context given, it appears you are asked to choose the correct pair as they are listed together in the question itself. 'Wrangling' and 'Precluding' are both verbs, but they have different meanings. 'Wrangling' refers to arguing or disputing, especially in a noisy or angry manner. 'Precluding' means to prevent something from happening or to make something impossible. There is no indicator in the provided question that suggests that only one of these words is to be chosen or that either is incorrect. Hence, both words are to be selected, making option c) the correct answer.
