Match the columns and find out the correct combination
`{:(,"Column I",,"ColumnII"),(a,"Treponema",(i),"Plague"),(b,"Yersinia pestis",(ii),"Anthrax"),(c,"Bacillus anthracis",(iii),"Syphilis"),(d,"Vibro",(iv),"Cholera"):}`

Options

A. (a)-(i),(b)-(iii),(c )-(ii),(d)-(iv)
B. (a)-(iii),(b)-(i),(c )-(ii)-,(d)-(iv)
C. (a)-(iv),(b)-(iii),( c)-(i),(d)-(ii)
D. (a)-(ii),(b)-(iii),( c )-(i), (d)-(iv)

Answer

To solve the matching question, we need to identify the correct combinations between the organisms in Column I and the diseases they cause in Column II. Let's go through each item step by step.

### Step-by-Step Solution:

1. **Identify the first organism: Treponema (a)**
- Treponema is known to cause **syphilis**, which is a sexually transmitted infection.
- Therefore, the match is: **(a) Treponema - (iii) Syphilis**.

2. **Identify the second organism: Yersinia pestis (b)**
- Yersinia pestis is the bacterium responsible for causing the **plague**.
- Therefore, the match is: **(b) Yersinia pestis - (i) Plague**.

3. **Identify the third organism: Bacillus anthracis (c)**
- Bacillus anthracis is known to cause **anthrax**, which can be deadly to livestock and humans.
- Therefore, the match is: **(c) Bacillus anthracis - (ii) Anthrax**.

4. **Identify the fourth organism: Vibrio (d)**
- Vibrio is associated with causing **cholera**, which is an acute diarrheal illness.
- Therefore, the match is: **(d) Vibrio - (iv) Cholera**.

### Summary of Matches:
- (a) Treponema - (iii) Syphilis
- (b) Yersinia pestis - (i) Plague
- (c) Bacillus anthracis - (ii) Anthrax
- (d) Vibrio - (iv) Cholera

### Final Combination:
The correct combination is:
- A - iii
- B - i
- C - ii
- D - iv

Thus, the answer is:
- **Option 2: A (iii), B (i), C (ii), D (iv)**.
