Which of the following is the cause of Wheat Blast, a disease that affects wheat crops?

Magnaporthe oryzae is a fast-acting fungal disease that is predicted to reduce global wheat production by 13% by 2050, according to researchers modeling the spread of wheat blast. Several grasses are impacted by wheat blast, primarily rice, lolium, barley, and wheat. It spreads by spores and contaminated seeds, and it thrives in warm, humid environments. It causes bleaching, lower yields, and poor seed quality and is resistant to fungicides; as a preventive measure, crop burning is necessary. Because of its severity, areas with climates that are vulnerable should remain vigilant at all times.
