B. 3-hydroxybutanoic acid and 2-hydroxypentanoic acid
C. 3-hydrocybutanoic acid and 3-hudroxypentanoic acid
D. 3-aminobutanoic acid and 3-hudroxypentanooc acid

Answer

To solve the question regarding the copolymerization process to obtain Poly Beta-hydroxybutyrate-co-Beta-hydroxy valerate (PHBV), we can break down the steps as follows:

### Step-by-Step Solution:

1. **Identify the Monomers**:
- The first monomer is **3-Hydroxybutyric acid**.
- The second monomer is **3-Hydroxypentanoic acid**.

2. **Chemical Structures**:
- The structure of **3-Hydroxybutyric acid** can be represented as:
\[ \text{CH}_3\text{CHOHCH}_2\text{COOH} \]
- The structure of **3-Hydroxypentanoic acid** can be represented as:
\[ \text{CH}_3\text{CH}_2\text{CH(OH)CH}_2\text{COOH} \]

3. **Understanding Copolymerization**:
- Copolymerization involves the chemical reaction between the two different monomers to form a copolymer. In this case, 3-Hydroxybutyric acid and 3-Hydroxypentanoic acid react to form PHBV.

4. **Formation of PHBV**:
- The reaction between these two acids leads to the formation of the copolymer PHBV, where the repeating units consist of both hydroxybutyrate and hydroxyvalerate units.

5. **Conclusion**:
- Therefore, the copolymer Poly Beta-hydroxybutyrate-co-Beta-hydroxy valerate (PHBV) is obtained by the copolymerization of **3-Hydroxybutyric acid** and **3-Hydroxypentanoic acid**.

### Final Answer:
PHBV is obtained by the copolymerization of **3-Hydroxybutyric acid** and **3-Hydroxypentanoic acid**.
