The correct similarity between oogenesis and spermatogenesis is that both occur inside the primary sex organs:

Oogenesis occurs in the ovaries (female primary sex organ).
Spermatogenesis occurs in the testes (male primary sex organ).
Other options are incorrect:

The growth phase in oogenesis is prolonged and starts before birth, but in spermatogenesis, it starts at puberty.
Oogenesis produces non-motile ova, while spermatogenesis produces motile sperm.
Oogenesis typically produces one viable gamete per cycle, while spermatogenesis produces millions of sperm continuously.
Thus, the correct answer is Option D.

Understanding Oogenesis and Spermatogenesis
Oogenesis and spermatogenesis are two distinct processes of gamete formation in females and males, respectively. Despite their differences, they share some similarities. Here, we focus on the similarity that both processes occur inside the primary sex organ.
Key Similarity: Location of Gamete Production
- Both oogenesis and spermatogenesis take place in the primary sex organs:
- Oogenesis occurs in the ovaries of females, where the development of ova (egg cells) takes place.
- Spermatogenesis occurs in the testes of males, where sperm cells are produced.
Distinct Characteristics of Oogenesis and Spermatogenesis
- Timing of Development:
- Oogenesis begins before birth and is characterized by a long growth phase, while spermatogenesis starts at puberty and continues throughout a male's life.
- Number of Gametes Produced:
- Oogenesis results in the formation of a limited number of ova (typically one per menstrual cycle), whereas spermatogenesis produces millions of sperm daily.
- Motility:
- Ova are non-motile, while sperm are motile due to their flagella.
Conclusion
In summary, while oogenesis and spermatogenesis are different in many aspects, they share the significant similarity of occurring within the primary sex organs. This location is crucial for the overall reproductive processes in both genders, ensuring that gametes are produced in the appropriate environment for successful fertilization and reproduction.
