The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Context**: The question asks about the susceptibility of chicks in their first two weeks in a brooder hoven to certain diseases. A brooder hoven is a controlled environment designed to keep chicks warm and safe as they grow. 2. **Analyzing the Options**: - **Option A: Marek's Disease**: This is a viral disease caused by the Marek's disease virus (an alpha herpesvirus). It is known to cause tumors and can affect chickens at any age, including juveniles and adults. Therefore, this option is not specific to the first two weeks. - **Option B: Ketosis**: This is a metabolic disorder primarily affecting cattle, not chickens. Thus, this option is irrelevant to the question. - **Option C: Ranikhet Disease**: Also known as Newcastle disease, this viral infection is caused by the Paramyxovirus. It primarily affects the respiratory system of chickens and is known to be more severe in juvenile chicks, making them particularly susceptible during their first two weeks. - **Option D: Whirling Disease**: This disease is caused by a parasitic protozoan (Myxobolus cerebellus) and primarily affects fish, not chickens. Hence, this option is also incorrect. 3. **Conclusion**: After analyzing all the options, the disease that specifically affects chicks in their first two weeks in a brooder hoven is **Option C: Ranikhet Disease** (Newcastle disease). **Final Answer**: C. Ranikhet Disease ---
