Solution

The correct option is C 8
  • Penicillium belongs to Ascomycetes which produces spores in asci called ascospores.
  • Single diploid ascus undergoes meiotic division and produces four haploid nuclei.
  • These four new nuclei undergo further mitotic division and produce four pairs of spores or 8 ascospores. Hence, the Number of ascospores formed in an ascus of Penicillium is 8.
  • So, the correct answer is "8'.
