On the basis of the availability of written records, early human history is commonly divided into —

On the basis of written evidence, the past is commonly classified as prehistoric, protohistoric and historic. Prehistory lacks written records, protohistory may have writing that is undeciphered or known indirectly, and history is supported by readable written sources. Prehistoric, Protohistoric and Historic periods fits that evidence because it matches the specific chronology, agency and function contained in the question. A comparison with the alternatives is useful: Palaeolithic and Neolithic periods only, Ancient and Medieval periods only and Stone, Bronze, Iron and Modern periods are genuine historical terms or names, but each belongs to a different office, patron, text, region or sequence. Reading the question as a relationship among person, period, place and institutional purpose prevents that mistake. The compact memory link is therefore Prehistoric, Protohistoric and Historic periods together with the factual context above, not the isolated option letter.
