The professor is using systematic sampling, as they are selecting every 8th name from the class list. Simple random sampling would involve randomly selecting 25 students from the entire class list, and convenience sampling would involve selecting the easiest or most readily available students, which does not seem to be the case here. Proportionate stratified random sampling would involve dividing the population into subgroups and selecting a proportionate number from each subgroup, which is also not happening here. Therefore, the best choice is D, systematic sampling.
