Casewise deletion involves discarding cases with missing responses, which can be a viable option if the amount of missing data is relatively small and the remaining sample size is still sufficient for analysis. However, it may introduce bias if the missingness is related to the variables being studied. Substitute a neutral value (option D) is not recommended as it can also introduce bias and distort the results of the analysis. Returning to the field (option A) may not be practical or feasible, and pairwise deletion (option C) may also introduce bias by excluding cases with missing data in some but not all of the variables being analyzed.
