B. Cylinder
✅ Explanation:
The cylinder dryer (also known as a drum dryer) is the most widely used dryer in the textile industry.

Wet fabric is passed in contact with the rotating hot cylinders.
The fabric dries as it comes into contact with the heated surface.
This dryer is highly suitable for woven and knitted fabrics.
🔹 Why it’s widely used:
Continuous drying process
Simple construction and operation
Efficient heat transfer
Well-suited for high-speed textile production
