The candidates present different scenarios of SNP arrangements, and the goal is to identify which combination is most likely to mislead due to tight linkage. The most misleading association is likely to arise from three SNPs tightly linked within a single LD block on one chromosome, as they may all reflect the same underlying genetic signal rather than independent contributions to the trait."}
