The orientation of long-axis of the cattle shed should be __________.

Correct option is A

Cattle Shed Orientation:
✅ North-South orientation is recommended for cattle sheds in tropical regions like India.
Advantages:
Ensures minimum direct sunlight exposure inside the shed during peak heat hours.
Sunlight enters from the sides only during early morning and late afternoon, keeping the shed cooler.
Improves ventilation and hygiene, reducing heat stress and disease risks.
Other Orientations:
❌ East-West – Causes excessive sunlight on one side throughout the day.
❌ Other directions – Not ideal for temperature and light regulation.
