The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Question**: The question asks for the definition of the gestation period. We need to identify which of the provided options correctly defines this term. 2. **Analyzing the Options**: - **Option A**: "The time period between the two successive phases in the menstrual cycle." This option does not relate to gestation, as it refers to the menstrual cycle rather than pregnancy. - **Option B**: "The time period required for trophoblast formation." This option is specific to early embryonic development but does not define the entire gestation period. - **Option C**: "The time period between implantation and parturition." This option correctly describes the gestation period, as it refers to the duration from when the embryo implants in the uterus until the birth of the young. - **Option D**: "None of these." This option can be eliminated since we have identified a correct option. 3. **Identifying the Correct Answer**: Based on the analysis, Option C is the correct answer. The gestation period is indeed the time from implantation of the embryo in the uterine wall to parturition (birth). 4. **Additional Information**: In humans, the gestation period typically lasts about 280 days, or approximately 40 weeks. **Final Answer**: The gestation period is the time period between implantation and parturition (Option C). ---
