Given below is a table of factors affecting microbial decomposition ('+' means 'favoring' and'-' means inhibiting or lowering). Select the correct option.
A) `{:("High temperature","Lack of oxygen","Moist enviorment","Lignin and chitin in destribus"),(+,+,+,-):}`
B) `{:("High temperature","Lack of oxygen","Moist enviorment","Lignin and chitin in destribus"),(+,-,+,-):}`
C) `{:("High temperature","Lack of oxygen","Moist enviorment","Lignin and chitin in destribus"),(-,-,+,-):}`
D) `{:("High temperature","Lack of oxygen","Moist enviorment","Lignin and chitin in destribus"),(-,+,+,-):}`

Options

A. `{:("High temperature","Lack of oxygen","Moist enviorment","Lignin and chitin in destribus"),(+,+,+,-):}`
B. `{:("High temperature","Lack of oxygen","Moist enviorment","Lignin and chitin in destribus"),(+,-,+,-):}`
C. `{:("High temperature","Lack of oxygen","Moist enviorment","Lignin and chitin in destribus"),(-,-,+,-):}`
D. `{:("High temperature","Lack of oxygen","Moist enviorment","Lignin and chitin in destribus"),(-,+,+,-):}`

Explanation

To solve the question regarding the factors affecting microbial decomposition, we will analyze each factor given in the options and determine whether they favor or inhibit decomposition.

### Step-by-Step Solution:

1. **Understanding the Factors**:
- **High Temperature**: Generally, higher temperatures increase the rate of microbial activity, thus favoring decomposition.
- **Lack of Oxygen**: Decomposition is an aerobic process, meaning it requires oxygen. A lack of oxygen inhibits decomposition.
- **Moist Environment**: Moisture is essential for microbial activity, so a moist environment favors decomposition.
- **Lignin and Chitin in Detritus**: Both lignin and chitin are complex compounds that are difficult for microbes to break down. Their presence inhibits decomposition.

2. **Analyzing Each Option**:
- **Option A**: `(+,+,+,-)`
- High Temperature: + (favors)
- Lack of Oxygen: + (favors) - Incorrect
- Moist Environment: + (favors)
- Lignin and Chitin: - (inhibits)
- **Conclusion**: Incorrect due to lack of oxygen.

- **Option B**: `(+,-,+,-)`
- High Temperature: + (favors)
- Lack of Oxygen: - (inhibits)
- Moist Environment: + (favors)
- Lignin and Chitin: - (inhibits)
- **Conclusion**: Correct option.

- **Option C**: `(-,-,+,-)`
- High Temperature: - (inhibits) - Incorrect
- Lack of Oxygen: - (inhibits)
- Moist Environment: + (favors)
- Lignin and Chitin: - (inhibits)
- **Conclusion**: Incorrect due to high temperature.

- **Option D**: `(-,+,+,-)`
- High Temperature: - (inhibits) - Incorrect
- Lack of Oxygen: + (favors) - Incorrect
- Moist Environment: + (favors)
- Lignin and Chitin: - (inhibits)
- **Conclusion**: Incorrect due to high temperature and lack of oxygen.

3. **Final Conclusion**: The correct option is **B**: `(+,-,+,-)`.
