• B. a-asexually, b-sexually
• C. a-asexually, b-parthenogenetically
• D. a-sexually, b-parthenogenetically

Answer 1

The correct option is B a-asexually, b-sexually

Cnidarians exhibit two basic body forms called polyp and medusa. Those cnidarians which exist in both forms exhibit alteration of generation (Metagenesis).
Thus, metagenesis is the process of alteration of sexual and asexual stage. Polyp is asexual stage and medusa is sexual stage.
Polyps produce medusae asexually by budding and medusae form the polyps by sexual reproduction. (Example- Obelia).

So, the correct answer is- polyp produce medusa asexually and medusa produce poly sexually (option b).
