B. Secondary deficiency
C. Primary deficiency
D. Complete deficieny

Answer

To answer the question, "Deficiency in plant growth and disorders caused by the reduced availability of a critical element is called," we need to analyze the provided options carefully.

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks about a deficiency in plant growth that arises from the reduced availability of a critical element. This implies that the element is still present but not in sufficient quantities for optimal growth.

2. **Evaluating the Options**:
- **Critical Deficiency**: This term refers to a situation where a deficiency leads to significant health risks or harmful effects. However, it does not specifically address the reduced availability of an element.
- **Secondary Deficiency**: This type of deficiency occurs when the body's ability to absorb a nutrient is impaired due to other medical conditions or illnesses. This does not relate to the reduced availability of the nutrient itself.
- **Primary Deficiency**: This deficiency occurs when there is an inadequate intake of a nutrient, leading to a lack of that nutrient in the plant. This aligns with the question as it directly relates to the reduced availability of a critical element.
- **Complete Deficiency**: This term describes a situation where a plant lacks sufficient amounts of various essential nutrients. It implies a total lack rather than a reduced availability.

3. **Identifying the Correct Answer**: Based on the analysis, the correct answer is **Primary Deficiency**. This is because it specifically refers to the lack of sufficient availability of a nutrient, which is what the question describes.

### Final Answer:
The deficiency in plant growth and disorders caused by the reduced availability of a critical element is called **Primary Deficiency**.
