Option D provides a clear and accurate definition of the term "error" in the context of regression analysis. Option A is incorrect because regression analysis seeks to identify and model relationships between variables. Option B is incorrect because while there is random error in regression analysis, it cannot be predicted with certainty. Option C is only partially correct, as while the estimates are derived from sample data, they are intended to serve as estimates for the population as a whole.
