d. Matched , because each person tries both A and B.
The matched test (or paired t-test or paired samples t-test or dependent t-test) is used when the data from the two groups can be presented in pairs, for example where the same people are being measured in before-and-after comparison or when the group is given two different tests at different times (eg. Tastes of two different types of Protieins).
