What is the primary statistical function of a t-test in psychological research?

Although there are different variations of the t-test to accommodate various research designs, its fundamental purpose is to serve as a null hypothesis test evaluating the statistical relationship between exactly two means.

Match each psychology research scenario with the specific variation of the $t$-test required to evaluate the relationship between the means.
