B Correct answer
Explanation

Sorghum downy mildew is caused by Peronosclerospora sorghi. It is diagnosed by chlorosis of the leaves that is followed by white streaking of the leaves. The white streaked areas of leaves become necrotic over time that leads to a shredded leaf appearance. In the maturing plant, the reproductive structures do not form properly or do not form at all. This leads to a sterile plant.
