A dependent-samples t-test should be used when studying the same group under two conditions because it compares the means of the same group at two different time points or situations. It is also known as a paired samples t-test. The other options are not appropriate for this scenario: independent-samples t-test compares the means of two groups, related-populations t-test compares two different populations, and correlation coefficient measures the relationship between two variables.
