 Bacterial leaf blight of rice is a serious disease caused by the bacterial pathogen Xanthomonas oryzae pv. oryzae. This disease can cause significant yield losses in rice crops, especially in areas with high humidity and rainfall. The pathogen infects the rice plant through wounds or natural openings, such as stomata, and causes water-soaked lesions on the leaves, which can turn brown and necrotic over time. Therefore, option 1 is the correct answer.
