• B. Paired t-test
• C. Chi-square test
• D. Standard deviation

Hint:

The paired t-test is a statistical test used to compare the means of a continuous variable measured on the same subjects before and after an intervention. This test accounts for the dependency between the two sets of data since the measurements are taken from the same individuals.
