Explanation:

Option A (Incorrect): Tests involving differences between means are parametric in nature. Nonparametric tests are employed when the data does not involve parameters or fails to meet distributional assumptions.
Option B (Correct): Nonparametric tests are utilized in three scenarios: 1) when the data does not meet distributional assumptions, 2) when the data is ranked, and 3) when the hypothesis does not pertain to a parameter.
Option C (Incorrect): If the data meets distributional assumptions, a parametric test is more appropriate than a nonparametric test.

This question assesses the understanding of when to apply nonparametric tests versus parametric tests in quantitative analysis.
