D. Implantation.

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the term that describes the release of oocytes or ova from the ovary.

2. **Identifying the Process**: The process of releasing an egg from the ovary is a specific biological event that occurs in the female reproductive cycle.

3. **Defining Ovulation**: The correct term for the release of the oocyte (egg) from the ovary is called "ovulation."

4. **Explaining the Ovulation Process**:
- During the menstrual cycle, the primary oocyte within the tertiary follicle grows in size.
- It completes its first meiotic division, which is an unequal division resulting in a large haploid secondary oocyte and a tiny polar body.
- The secondary oocyte retains most of the cytoplasm and nutrients.
- The tertiary follicle then transforms into a mature follicle, also known as the Graafian follicle.
- The Graafian follicle eventually ruptures, releasing the secondary oocyte from the ovary.

5. **Conclusion**: Therefore, the release of oocytes or ova from the ovary is specifically termed "ovulation."

**Final Answer**: The release of oocytes/ova from the ovary is called ovulation.
