The most suitable t-test for measuring developmental changes over time would be the two-sample t-test with repeated measures design. This design involves testing the same group of individuals at different time points, allowing for the examination of within-subject changes over time. The two-sample t test with independent samples design (option B) involves testing two different groups of individuals and would not be appropriate if the goal is to measure changes within a single group over time. The one-sample t test (option A) would also not be suitable as it only compares one sample mean to a known population mean.
