In an epigynous flower, the ovary is inferior (located below other floral parts), and the other floral parts (such as petals, sepals, and stamens) are superior (situated above the ovary). This type of flower has a "half-inferior" ovary, meaning the other floral parts appear to arise from above the ovary.
Thus, the correct answer is (B) : Ovary is inferior and other floral parts are superior.
