Options

A. Parrot, cockroach, Melandrium and honey bee
B. Grasshopper, Drosophila , Aptenodytes, and Apis
C. Grasshopper, Pavo, man and honey bee
D. Grasshopper, hen , cockroach and Apis

Answer

To solve the question regarding the organisms that exhibit XO, XY, ZW, and haplodiploid types of sex determination, we will analyze each type of sex determination and identify the respective organisms.

### Step-by-Step Solution:

1. **Understanding XO Type of Sex Determination**:
- In the XO system, females have two X chromosomes (XX), while males have only one X chromosome (XO), meaning they lack a second sex chromosome.
- This type of sex determination is commonly found in **insects**, such as **cockroaches**.

2. **Understanding XY Type of Sex Determination**:
- In the XY system, males have one X and one Y chromosome (XY), while females have two X chromosomes (XX).
- This system is typical in **humans** and many other mammals, as well as in **Drosophila** (fruit flies).

3. **Understanding ZW Type of Sex Determination**:
- In the ZW system, females have one Z and one W chromosome (ZW), while males have two Z chromosomes (ZZ).
- This type of sex determination is primarily found in **birds**, such as **peacocks** and **chickens**.

4. **Understanding Haplodiploid Type of Sex Determination**:
- In the haplodiploid system, males develop from unfertilized eggs and are haploid (n), while females develop from fertilized eggs and are diploid (2n).
- This system is characteristic of **honey bees** (Apis).

5. **Identifying the Correct Organisms for Each Type**:
- Now, we can summarize:
- **XO**: Cockroach (insects)
- **XY**: Humans or Drosophila
- **ZW**: Birds (e.g., peacock)
- **Haplodiploid**: Honey bee (Apis)

6. **Evaluating the Options**:
- We need to find the option that correctly matches these organisms to their respective sex determination types.
- After evaluating the options provided in the question, we find that **Option 2** correctly lists:
- Grasshopper (XO)
- Drosophila (XY)
- Birds (ZW)
- Honey bee (Haplodiploid)

### Final Answer:
**Option 2** is the correct answer.
