Explanation

To find the incorrect match from the given options, we will analyze each option step by step.

### Step 1: Analyze Option A
- **Match**: Hemoglobin - Magnesium
- **Explanation**: Hemoglobin is a protein in red blood cells that carries oxygen. The key component of hemoglobin is iron (Fe), not magnesium (Mg). Therefore, this match is incorrect.

### Step 2: Analyze Option B
- **Match**: Fertilizer - Nitrogen and Phosphorus
- **Explanation**: Nitrogen and phosphorus are essential nutrients found in many fertilizers. They are known to promote plant growth. Thus, this match is correct.

### Step 3: Analyze Option C
- **Match**: Chlorophyll - Iron
- **Explanation**: Chlorophyll is the green pigment in plants responsible for photosynthesis. The key component of chlorophyll is magnesium (Mg), not iron (Fe). Therefore, this match is also incorrect.

### Step 4: Analyze Option D
- **Match**: Both A and C
- **Explanation**: Since both A (Hemoglobin - Magnesium) and C (Chlorophyll - Iron) are incorrect matches, this option correctly identifies that both A and C are wrong.

### Conclusion
- The incorrect matches are found in options A and C. Therefore, the correct answer to the question "Find the incorrect match" is option D, which states that both A and C are incorrect.
