Answer is B. You use ANCOVA for this.
In ANCOVA we evaluate if the means of a dependent variable are equal across levels of a categorical independent variable (IV) often called a treatment, while statistically controlling for the effects of other continuous variables that are not of primary interest, known as covariates (CV) or nuisance variables.

Consider the following data from a repeated-measures design. You want to use a repeated-measures t test to test the null hypothesis H_0: mu_D = 0 (the null hypothesis states that the mean difference for the general population is zero). The data consist of five observations, each with two measurements, A and B, taken before and after a treatment. Assume the population of the differences in these measurements are normally distributed. Complete the following table by calculating the differences and the...

The researcher from Q2 decided that they want to follow up with
the 6 children one year after they have completed the intervention
program to see how they are now coping with negative emotions. The
same method of assessment was used to examine coping responses. The
data for the one-year follow-up list is listed below (along with
results from Q2).
