Which of the following is a widely grown high-yielding paddy variety known for being semi-dwarf and introduced during the Green Revolution?
Explanation: IR8 is a high-yielding, semi-dwarf rice variety developed during the Green Revolution and helped increase rice production. Basmati is renowned for its aroma and long grain but is not primarily bred for high yield. Japonica is a rice group common in temperate regions but not associated with semi-dwarf or the Green Revolution. Golden Rice is genetically modified for increased vitamin A content, not specifically high yield.
Which paddy variety is prized internationally for its long, slender grains and distinctive aroma, often used in festive dishes?
Explanation: Basmati rice is famous for its unique aroma and long, slender grains, making it a staple at special occasions. Sona Masuri and Samba Mahsuri are popular medium-grain varieties with less distinct aroma. Red Rice refers to varieties with reddish bran and is not known for aroma or slender grains.
Which of these varieties is best suited for upland, rainfed conditions where waterlogging does not occur?

A farmer in a flood-prone region is advised to sow which specialized paddy variety, developed to survive extended submergence?
