What was the famous medieval Mughal building material used for the Taj Mahal?

The correct answer is White marble from Makrana Rajasthan. The question asks: “What was the famous medieval Mughal building material used for the Taj Mahal?” The Taj Mahal was built primarily of white marble quarried from Makrana in Rajasthan. The marble was transported 200 miles by elephants and ox carts. Precious stones from across Asia were inlaid in the marble. The key to solving this item is to identify exactly what the question tests—the relevant ruler, event, institution, work, place, policy, date, or historical association—and then connect that clue with White marble from Makrana Rajasthan. This direct association is more reliable than choosing an option merely because it belongs to the same broad medieval period. The remaining choices—Red sandstone, Black granite, Both red sandstone and white marble—serve as distractors. Candidates should therefore compare each option with the precise wording, period, agency, and outcome mentioned in the stem. This method prevents confusion between contemporary personalities, similarly named monuments, successive dynasties, and events from neighbouring reigns. It is also useful to place the fact on a short chronology and ask whether the person or institution could plausibly belong to that time. The answer is thus not a guess based on familiarity: it follows from the question-specific connection between White marble from Makrana Rajasthan and the subject asked in the stem.
