C)planned comparison
D)post-hoc comparison

A planned comparison is a specific comparison that is pre-planned and based on a specific hypothesized condition or contrast. It tests for differences between specific cells in the experimental design, while controlling for error rates. Internal comparison refers to comparing different measurements or outcomes within the same group or individual, whereas non-experimental comparison does not involve the manipulation of an independent variable. Post-hoc comparison refers to conducting multiple comparisons after observing significant results, which increases the risk of type I errors. Therefore, the best choice in this case is C, planned comparison.
