The correct Answer is:
To answer the question regarding the intrinsic factors that affect development in plants, we can follow these steps: ### Step-by-Step Solution: 1. **Understanding Intrinsic Factors**: - Intrinsic factors are internal factors that influence the development of plants. These include genetic makeup and hormonal influences. 2. **Identifying the Options**: - We have four options to evaluate: - Option 1: Light, water, and oxygen - Option 2: Oxygen, genetic, and plant growth regulators - Option 3: Genetic and plant growth regulators - Option 4: Water, temperature, and plant growth regulators 3. **Analyzing Each Option**: - **Option 1**: Light, water, and oxygen are external factors that affect plant growth, not intrinsic. - **Option 2**: While it includes genetic factors, oxygen is an external factor. - **Option 3**: This option includes genetic factors and plant growth regulators, both of which are intrinsic factors. - **Option 4**: Water and temperature are external factors, while plant growth regulators are intrinsic. 4. **Conclusion**: - The only option that consists solely of intrinsic factors is **Option 3: Genetic and plant growth regulators**. ### Final Answer: The intrinsic factors that affect development in plants are **genetic factors and plant growth regulators**. ---
