Read the following statements
(i) Mule is developed by interspecific hybridisation
(ii) Group of bees is called 'swarms'
(iii) For the herd-improvement cross-breeding is employed
(iv) Bees are the pollinators of apple, brassica, pear and sunflower
(v) In MOET , fertilised egg at 6-8 celled stage is recovered non-surgically

Options

A. I,ii,iii,iv, are true
B. iii,iv,I are false
C. I,ii,iv are true
D. I,ii,iii ,iv and v are true

Answer

To determine the truthfulness of the statements provided, we will analyze each statement one by one.

### Step-by-Step Solution:

1. **Statement (i)**: "Mule is developed by interspecific hybridisation."
- A mule is produced by crossing a female horse (Equus caballus) with a male donkey (Equus asinus). This process involves two different species, hence it is classified as interspecific hybridization.
- **Conclusion**: This statement is **True**.

2. **Statement (ii)**: "Group of bees is called 'swarms'."
- The term "swarms" refers to the group of bees that leave the original colony to form a new one, typically led by a queen bee. Therefore, this statement is accurate.
- **Conclusion**: This statement is **True**.

3. **Statement (iii)**: "For the herd-improvement cross-breeding is employed."
- Cross-breeding is a technique used to improve the genetic quality of livestock. It involves mating animals from different breeds to produce hybrids that exhibit desirable traits, thus aiding in herd improvement.
- **Conclusion**: This statement is **True**.

4. **Statement (iv)**: "Bees are the pollinators of apple, brassica, pear and sunflower."
- Bees play a crucial role in pollination for many crops, including apple, brassica (cabbage family), pear, and sunflower. They help in the transfer of pollen from one flower to another, facilitating fertilization.
- **Conclusion**: This statement is **True**.

5. **Statement (v)**: "In MOET, fertilised egg at 6-8 celled stage is recovered non-surgically."
- In the Multiple Ovulation Embryo Transfer (MOET) technology, females are induced to produce multiple eggs, which are fertilized. The fertilized eggs, typically at the 6-8 cell stage, can be recovered non-surgically and transferred to surrogate mothers.
- **Conclusion**: This statement is **True**.

### Final Conclusion:
All five statements are true. Therefore, the correct option is that **1st, 2nd, 3rd, 4th, and 5th are true**.
