Solution

The correct option is B Is a sac fungus
Ergot of rye is the disease caused by Claviceps purpurea (rye ergot fungus). It affects the rye plants. The fungus produces alkaloids which cause ergotism in humans who consume contaminated grains. The fungus belongs to Ascomycota (sac fungi) group. It has septate hyphae. It reproduces asexually by non-motile conidiospores and sexually by ascospores.
So, the correct option is 'is a sac fungus.'
