Which one of the following is the semi- dwarf high-yielding variety of Basmati rice developed by India?

Kasturi is the first semi-dwarf, high-yielding variety (HYV) of Basmati rice developed in India. It was released by the Indian Agricultural Research Institute (IARI) to combine the traditional aromatic qualities of Basmati with the high-yield potential of dwarf varieties. While traditional Basmati varieties are tall and prone to lodging, Kasturi's semi-dwarf nature allows for better nutrient response and higher productivity [t1]. Other options like Sindhu (a seedless mango variety), Rathna (a rice variety but not a primary Basmati HYV), and Mallika (a mango variety) do not fit the description. The development of such varieties was part of India's broader effort to enhance food security and export potential by applying Green Revolution breeding techniques to premium aromatic rice [t3].
