Identify the blanks spaces A,B,C and D in the following table and select the correct answer.
`{:("Type of microbe","Scientific name","Commercial product"),("Bacterium",A,"Lactic acid"),("Fungus",B,"Cyclosporin A"),(C,"Monascus purpureus","Statins"),("Fungus","Penicillium notatum",D):}`

Options

A. A-Lactobacillus B-Trichoderma polysporum
C-Yeast D-Penicillin
B. A-Acetobacter B-Trichoderma polysporum
C-Yeast D-Streptomycin
C. A-Lactobacillus B-Aspergillus niger
C-Algae D-Penicillin
D. A-Lactobacillus B-Trichoderma polysporum
C-Agaricus D-Penicillin

Answer

To identify the blank spaces A, B, C, and D in the provided table, we need to fill in the scientific names and commercial products associated with the respective types of microbes.

1. **Row 1: Bacterium producing Lactic Acid**
- The type of microbe is a bacterium, and the commercial product is lactic acid. The scientific name for the bacterium that produces lactic acid is **Lactobacillus**.
- **A = Lactobacillus**

2. **Row 2: Fungus producing Cyclosporin A**
- The type of microbe is a fungus, and the commercial product is cyclosporin A. The scientific name for the fungus that produces cyclosporin A is **Trichoderma polysporum**.
- **B = Trichoderma polysporum**

3. **Row 3: Microbe producing Statins**
- The scientific name given is **Monascus purpureus**. This is a type of fungus (specifically a yeast) that produces statins, which are used to lower cholesterol.
- **C = Fungus**

4. **Row 4: Fungus producing Penicillin**
- The scientific name provided is **Penicillium notatum**, and the commercial product obtained from it is penicillin, which is a well-known antibiotic.
- **D = Penicillin**

Now, let's summarize the filled table:

| Type of microbe | Scientific name | Commercial product |
|------------------|---------------------------|--------------------|
| Bacterium | Lactobacillus | Lactic acid |
| Fungus | Trichoderma polysporum | Cyclosporin A |
| Fungus | Monascus purpureus | Statins |
| Fungus | Penicillium notatum | Penicillin |

### Final Answers:
- A = Lactobacillus
- B = Trichoderma polysporum
- C = Fungus
- D = Penicillin
