The correct option is C Diplobiontic
Saccharomycodes ludwigii and some other yeasts have diplobiontic type of life cycle. In these yeasts, the vegetative stage is predominantly diploid and the haploid stage is very short. In this type, the ascospores are not liberated from the ascus but they copulate within the ascus. The zygotes found within the ascus bud out diplobiontic vegetative cells.
