I believe that the answer to this topic is incorrect. Per the above URL for sql2008, both Enterprise and Standard editions support Snapshot Replication. As Developer and Enterprise editions support the same feature sets, it would not make sense to select that choice as it would not cover the Standard edition. Therefore I believe that my answer is correct (Dev + Std). Another alternative would have been Standard, Enterprise, and Developer editions (which would have been the best answer).
