A sequential sample is determined by a series of decisions as the data are collected. The number of elements to be sampled is not decided in advance, but determined by the researcher's ongoing assessment of the data collected. Quota sampling is a non-probability sampling technique where the researcher decides in advance the number of participants needed for each subgroup, so it is not the correct choice. Accidental sampling is a type of non-probability sampling where individuals are selected based on their availability, so it does not apply here either. Fixed sampling is a type of probability sampling where the sample size is determined in advance and remains constant throughout the research process, which is not the case here. Therefore, the best choice is A, sequential.
