Given below are two statements (A-B) each with one or more blanks. Select the option which correctly fills the blanks in the statements -
Statements :
A. Bioactive molecule, .................is used as Immunosuppressive agent in organ transplant patients, It is produced by the fungus.................
B. Primary treatment of sewage involves physical removal of small and large particles through Options

Options

A. A-Antibiotic, Trichoderma polysporum, B - filtration and sedimentation
B. A-Cyclosporin A, Trichoderma polysporum, B - filtration and sedimentation
C. A-Cyclosporin A, Trichoderma polysporum, B-Centrifugation and sedimentation
D. A-Antibiotic, Trichoderma polysporum, B - Centrifugation and sedimentation

Answer

To solve the given statements, we need to identify the correct bioactive molecule and the fungus that produces it, as well as the method of primary sewage treatment.

### Step-by-Step Solution:

1. **Identify the Bioactive Molecule:**
- The bioactive molecule used as an immunosuppressive agent in organ transplant patients is **Cyclosporin**. It helps prevent organ rejection by suppressing the immune response.

2. **Identify the Fungus:**
- Cyclosporin is produced by the fungus **Tolypocladium inflatum**. This fungus is known for its ability to produce this important immunosuppressive drug.

3. **Complete Statement A:**
- Therefore, Statement A can be completed as:
- "Bioactive molecule, **Cyclosporin** is used as an immunosuppressive agent in organ transplant patients. It is produced by the fungus **Tolypocladium inflatum**."

4. **Understand Primary Treatment of Sewage:**
- The primary treatment of sewage involves the physical removal of small and large particles. This is typically done through processes such as **screening and sedimentation**.

5. **Complete Statement B:**
- Therefore, Statement B can be completed as:
- "Primary treatment of sewage involves physical removal of small and large particles through **screening and sedimentation**."

### Final Completed Statements:
- A. Bioactive molecule, **Cyclosporin** is used as an immunosuppressive agent in organ transplant patients. It is produced by the fungus **Tolypocladium inflatum**.
- B. Primary treatment of sewage involves physical removal of small and large particles through **screening and sedimentation**.
