Match and find the correct combination
`{:(,(a),HIV,i,Ghost),(,(b),"Pilus",(ii),"Prophage"),(,(c),"Virus",(iii),"Retro viridae"),(,(d),"Lysogeny",(iv),"Donor"):}

Options

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

Answer

To solve the matching question, we need to pair each item from the left column with the correct item from the right column based on their definitions and relationships. Let's break it down step by step.

### Step-by-Step Solution:

1. **Identify the first item: HIV**
- HIV stands for Human Immunodeficiency Virus. It is known to cause AIDS and belongs to the family of retroviruses.
- **Match:** (a) HIV → (iii) Retroviridae

2. **Identify the second item: Pilus**
- A pilus is a hair-like structure on the surface of bacteria that facilitates the transfer of genetic material during a process called conjugation. The bacterium that donates genetic material is referred to as the donor.
- **Match:** (b) Pilus → (iv) Donor

3. **Identify the third item: Virus**
- Viruses can enter a lysogenic cycle where they integrate their DNA into the host's DNA. This integrated viral DNA is referred to as a prophage.
- **Match:** (c) Virus → (ii) Prophage

4. **Identify the fourth item: Lysogeny**
- Lysogeny is the process by which a virus integrates its genetic material into the host's genome. The phase where the viral DNA is integrated is called the prophage.
- **Match:** (d) Lysogeny → (i) Ghost

### Final Matching Combinations:
- (a) HIV → (iii) Retroviridae
- (b) Pilus → (iv) Donor
- (c) Virus → (ii) Prophage
- (d) Lysogeny → (i) Ghost

### Summary of Correct Combinations:
1. (a) HIV → (iii) Retroviridae
2. (b) Pilus → (iv) Donor
3. (c) Virus → (ii) Prophage
4. (d) Lysogeny → (i) Ghost
