B. Olfactory-Smell
C. Algesirceptor-Pain
D. Organ of corti-Sensory and suporting cells.

Answer

To solve the question "Which one is the incorrect match?", we will analyze each option provided in the question.

### Step-by-Step Solution:

1. **Identify the Options**: We have four options to evaluate. The first option is "myopia by convex lens", the second is "olfactory is to smell", the third is "LJC receptor is to pain", and the fourth is "Organ of Corti, these are sensory and supporting cells".

2. **Evaluate the First Option**:
- **Myopia**: This is a condition also known as short-sightedness, where distant objects appear blurry because light rays focus in front of the retina.
- **Lens Used**: To correct myopia, concave lenses are used, not convex lenses. Therefore, the statement "myopia by convex lens" is incorrect.

3. **Evaluate the Second Option**:
- **Olfactory**: This term is indeed related to the sense of smell.
- **Conclusion**: This option is correct.

4. **Evaluate the Third Option**:
- **LJC Receptor**: These receptors are responsible for detecting pain.
- **Conclusion**: This option is also correct.

5. **Evaluate the Fourth Option**:
- **Organ of Corti**: This structure is located in the cochlea of the inner ear and contains sensory and supporting cells that are crucial for hearing.
- **Conclusion**: This option is correct as well.

6. **Final Conclusion**: After evaluating all options, the only incorrect match is the first option: "myopia by convex lens". Therefore, the answer is A.

### Final Answer:
The incorrect match is **A: Myopia by convex lens**.
