Sunflower is a major oilseed crop grown during which season in Karnataka?

Kharif
Rabi
Both seasons
Throughout the year

The correct answer is: A) Kharif.

Sunflower is a major oilseed crop grown during the Kharif season in Karnataka. The Kharif season is the rainy season in India, which runs from June to September. Sunflower is a warm-season crop that requires a lot of sunlight and water. It is planted in the rainy season and harvested in the winter.

The other options are incorrect. Rabi is the winter season in India, which runs from October to March. Sunflower is not a cold-season crop and cannot be grown during the Rabi season. Both seasons is also incorrect, as sunflower is only grown during the Kharif season. Throughout the year is also incorrect, as sunflower is a seasonal crop that can only be grown during the Kharif season.
