In the Later Vedic period, which deity gained the position of supreme creator in place of Indra?

Vishnu and Rudra also rose in importance, but Prajapati is the standard answer to this formulation. Prajapati fits that evidence because it matches the specific chronology, agency and function contained in the question. A comparison with the alternatives is useful: Vishnu, Shiva and Agni 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 supporting source also helps separate later textbook shorthand from the more precise historical formulation. The compact memory link is therefore Prajapati together with the factual context above, not the isolated option letter.
