To dummy code this question, a researcher would need to create 3 dummy variables (D1, D2, and D3). This is because there are 4 possible responses, and we only need 3 dummy variables to represent all possible response categories. The reference category would be "none of it." The dummy variable D1 would represent "some of it," D2 would represent "most of it," and D3 would represent "all of it." Therefore, the correct answer is C.
