Answer:
D). Conducting ethnological analysis.
Step-by-step explanation:
As per the given description, the comparison would require 'conducting an ethnological analysis' which is exemplified as the element of anthropology that focuses primarily on comparing and evaluating the distinct human cultures and their characteristics. Such an analysis would comprehend the analysis of 'fieldwork on Mormon fundamentalists and the marriage pattern followed in their culture and comparing it to the Muslim tradition' as it provides the scope for exploring the culture and unclaimed issues lying in the particular culture or its systems that would make the fieldwork more effective. Therefore, option D is the correct answer.
