Explanations: A good research design must be unbiased to ensure that the results are not skewed by any systematic errors. It should also be free from confounding effects, which are extraneous variables that can distort the relationship between the independent and dependent variables. Additionally, statistical precision is crucial to ensure that the results are reliable and can be generalized to a larger population. Therefore, all these characteristics are essential for a good research design.

Option Analysis:

Option A: Unbiased in nature is a key characteristic of a good research design.
Option B: Free from confounding effect is another critical characteristic.
Option C: Statistical precision is also an important characteristic.
