01 Numismatics is related to the study of which historical source?
Answer and explanation
Correct answer: D. Coins
Explanation: Numismatics is the specialised study of coins and other forms of currency used in the past. Coins are historical sources because their metal, shape, weight, inscriptions, symbols, and images can provide clues about rulers, political authority, trade, economic conditions, and the circulation of money. Historians compare coins with other evidence instead of treating one coin as a complete account of the past.
Option D is correct because “numismatics” comes from a term connected with coins and currency. Poems may be studied as literary sources, caves as archaeological sites or rock-art locations, and bones as biological or archaeological evidence. None of these is the direct subject named by numismatics. Thus, the correct historical source is coins, even though coins can also help researchers learn about wider economic and political life.
