`{:("Name of Organisms","Chromosome number in gametes"),("Butterfly",6),("Housefly",39),("Dog",21),("Cat",19),("Rat",190):}`

Options

A. a-5,b-1,c-2,e-3,d-4
B. b-1,e-2,d-3,c-4,a-5
C. e-1,a-2,b-3,d-4,c-5
D. e-1,a-2,c-3,b-4,d-5

Explanation

To solve the problem of matching the organisms with their respective chromosome numbers in gametes, we will follow these steps:

### Step-by-Step Solution:

1. **Identify the Organisms and Chromosome Numbers**:
- We have the following organisms: Butterfly, Housefly, Dog, Cat, and Rat.
- The corresponding chromosome numbers in gametes are given as: 6, 39, 21, 19, and 190.

2. **Match Each Organism with the Correct Chromosome Number**:
- **Butterfly**: The correct chromosome number in gametes is **190**.
- **Housefly**: The correct chromosome number in gametes is **6**.
- **Dog**: The correct chromosome number in gametes is **39**.
- **Cat**: The correct chromosome number in gametes is **19**.
- **Rat**: The correct chromosome number in gametes is **21**.

3. **Create the Matching Pairs**:
- A: Butterfly - 190
- B: Housefly - 6
- C: Dog - 39
- D: Cat - 19
- E: Rat - 21

4. **Final Matching**:
- A (Butterfly) matches with 190.
- B (Housefly) matches with 6.
- C (Dog) matches with 39.
- D (Cat) matches with 19.
- E (Rat) matches with 21.

5. **Choose the Correct Combination from the Options**:
- Based on the matches, we can identify the correct option from the provided choices.

### Final Answer:
The correct combination is:
- A (Butterfly) - 190
- B (Housefly) - 6
- C (Dog) - 39
- D (Cat) - 19
- E (Rat) - 21
