The independent t-test is typically used when there are two experimental conditions (such as a control group and an experimental group) and different participants are used in each condition. This allows for comparison between the two groups and determining if there is a statistically significant difference between them. Option A involves only one condition and is not appropriate for independent t-test. Option B involves the same participants in both conditions, which would require a paired t-test. Option D is not a valid option as it does not provide any information.
