D.1, 2 and 3
Explanation & Solution

The correct answer is (C) 3 only.

Explanation:

We need to find which statements are NOT correct based on the given premise: "No supporters of 'party X', who knew Z and supported his campaign strategy, agreed...". Statement 1: "Some supporters of 'party X' knew Z." This is correct because the premise references a group of people who are "supporters of party X, who knew Z and supported his strategy," implying such a group exists. Statement 2: "Some supporters of 'party X', who opposed Z's campaign strategy, knew Z." There is no information in the premise about supporters who opposed Z's strategy, so this statement is not correct (cannot be inferred). Statement 3: "No supporters of 'party X' supported Z's campaign strategy." This contradicts the premise which establishes that some supporters did support his campaign strategy. Thus, this statement is definitely not correct. Therefore, statements 2 and 3 are not correct, making Option B the correct choice.
