Concept & Option Breakdown
Standard Reference VerifiedOption (a) is correct: The Baudhayana Sulba Sutra (c. 8th century BCE) provides the earliest Indian formulation of what is commonly known as the Pythagorean theorem. It geometrically formulates that the diagonal of a rectangle produces by itself both the areas which the length and breadth produce separately (the relationship between the sides and hypotenuse of a right-angled triangle), primarily utilized for designing fire altars (vedis).
Sulba Sutras are ancient texts on sacrificial geometry dealing with geometric constructions of altars using cords (sulba), fundamentally based on right-triangle properties.
