B. Development of fruit without fertilization
C. Development of fruit without hormones
D. Development of embryo from egg without fertilization

Answer

**Step-by-Step Text Solution:**

1. **Understanding Parthenogenesis**: Parthenogenesis is a form of asexual reproduction where an embryo develops from an unfertilized egg. This means that fertilization by sperm is not necessary for the development of the offspring.

2. **Identifying the Options**: The question provides four options:
- A) Development of embryo without fertilization
- B) Development of fruit without fertilization
- C) Development of fruit without hormones
- D) Development of embryo from egg without fertilization

3. **Analyzing the Correct Option**:
- Option A describes the development of an embryo without fertilization, which is partially correct but does not specify that it comes from an egg.
- Option B discusses fruit development, which is not related to parthenogenesis.
- Option C also refers to fruit development and hormones, which is irrelevant.
- Option D clearly states the development of an embryo from an egg without fertilization, which accurately defines parthenogenesis.

4. **Conclusion**: Based on the definitions and options provided, the correct answer is option D: "Development of embryo from egg without fertilization."

**Final Answer**: Option D - Development of embryo from egg without fertilization.
