Solution
The correct option is A Ustilago
Ustilago is a genus of approximately 200 smut fungi parasitic on grasses. In the haplontic life cycle, the haploid stage is multicellular and the diploid stage is a single cellular. The zygote undergoes meiosis to form haploid spores. Each spore germinates (divide mitotically) to form gametophyte.
So, the correct answer is option A.
