Which was the world- famous treatise of the amorous arts?

Answer: Option A

The Kamasutra is an ancient Indian Sanskrit text on sexuality, eroticism and emotional fulfillment in life. Attributed to Vatsyayana, the Kama Sutra is neither exclusively nor predominantly a sex manual on sex positions, but written as a guide to the "art-of-living" well, the nature of love, finding a life partner, maintaining one's love life, and other aspects pertaining to pleasure-oriented faculties of human life.
