Spearman's rank correlation test would be the best choice to determine whether the two scouts have similar opinions. This test measures the degree of association between the two rankings provided by the scouts, and determines if there is a significant correlation between them. It is appropriate for nonparametric data, which is the case in this scenario. The other tests (A, B, C, and D) do not measure the degree of association between the rankings, and are not appropriate for this scenario.
