The question does not provide information about which measurement is larger or smaller, so it is not possible to determine if one ruler is more accurate than the other. However, the question does suggest that there is a slight difference in the measurements taken with the two rulers. The only option that accounts for this slight difference without exaggerating it is choice C, which states that ruler A has one more significant digit than ruler B. This suggests that ruler A has finer measurement markings than ruler B, but not by a significant amount.
