The correct Answer is:
### Step-by-Step Solution: 1. **Identify Symptoms**: The plant is exhibiting symptoms such as chlorosis (yellowing) of younger or older leaves, production of sterile flowers, and the presence of grey spots. 2. **Analyze Each Symptom**: - **Chlorosis**: This symptom indicates a lack of chlorophyll, which can be caused by several nutrient deficiencies. - **Sterile Flowers**: This suggests a problem with reproductive health, which can also be linked to specific nutrient deficiencies. - **Grey Spots**: This could indicate necrosis or tissue damage, often associated with certain nutrient deficiencies. 3. **Consider Possible Nutrient Deficiencies**: - **Manganese Deficiency**: Known to cause chlorosis in young leaves, sterile flowers, and grey spots. - **Boron Deficiency**: Affects cell growth but does not typically cause the symptoms described. - **Potassium Deficiency**: Leads to yellowing of leaf margins and curling of leaf tips, which are not the symptoms mentioned. - **Calcium Deficiency**: Affects overall plant growth and can lead to the death of terminal buds and root tips, but does not match the symptoms given. 4. **Conclusion**: Based on the symptoms presented, the most likely cause of the plant's condition is a deficiency of manganese. ### Final Answer: The deficiency causing the symptoms is **Manganese**. ---
