The correct Answer is:
### Step-by-Step Solution: 1. **Identify the Organism**: The question pertains to Hydra, which is a member of the phylum Cnidaria and class Hydrozoa. 2. **Understand the Regeneration Process**: Hydra has a remarkable ability to regenerate lost parts due to its tissue regeneration properties. This means that if a Hydra is cut into two pieces, each piece has the potential to develop into a new Hydra. 3. **Analyze the Cutting Scenario**: When Hydra is cut into two pieces, one piece will contain the head (or mouth) and the other will contain the foot (or basal disc). Each piece will regenerate the missing part: - The piece with the head will regenerate a new foot. - The piece with the foot will regenerate a new head. 4. **Evaluate the Options**: - **Option 1**: Growth without mouth and basal disc - This is incorrect because regeneration will occur. - **Option 2**: Growth of mouth and disc according to their position in the parent - This is correct as each piece regenerates the missing part based on its original position. - **Option 3**: Growth of mouth and disc at any end - This is incorrect as regeneration is dependent on the original position. - **Option 4**: No regeneration is possible - This is incorrect since Hydra has the ability to regenerate. 5. **Conclusion**: The correct answer is **Option 2**: Growth of mouth and disc according to their position in the parent.
