Options
A Primary mycelium
B Dikaryotic stage

D Haploid basidiospore
Correct Answer

Option B is the correct answer.

The dikaryotic stage of the basidiomycete life cycle contains haploid nuclei of two different mating strains. This stage results when mycelia of different mating strains combine and produce a secondary mycelium, and it is the dominant stage of the basidiomycete lifecycle.

The term means 'two nuclei' and represents the prolonged stage between plasmogamy and karyogamy.
