The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Question**: The question asks about the process that induces flowering in plants through low temperature treatment. 2. **Identifying the Options**: The options provided are: - Option 1: Vernalization - Option 2: Cryobiology - Option 3: Photoperiodism - Option 4: Pruning 3. **Analyzing Option 1 - Vernalization**: Vernalization is a well-known process in botany where exposure to low temperatures promotes flowering in certain plants. This is particularly important for plants that require a cold period to trigger their flowering mechanism. 4. **Analyzing Option 2 - Cryobiology**: Cryobiology is the study of the effects of low temperatures on living organisms. While it involves low temperatures, it does not specifically refer to the process of inducing flowering. 5. **Analyzing Option 3 - Photoperiodism**: Photoperiodism refers to the physiological reaction of organisms to the length of day or night. It is related to flowering but is not directly linked to low temperature treatment. 6. **Analyzing Option 4 - Pruning**: Pruning is a horticultural practice that involves the selective removal of plant parts to improve growth or flowering. It does not involve low temperature treatment. 7. **Conclusion**: Based on the analysis, the correct answer is **Option 1: Vernalization**, as it specifically refers to the induction of flowering through low temperature treatment. **Final Answer**: The induction of flowering by low temperature treatment is called **Vernalization**. ---
