Fabric Care

Step 1: Understanding water extraction in washing machines.
After washing and rinsing, clothes contain a large amount of water. Washing machines use different mechanisms to remove this excess water before drying. The efficiency of water removal depends on the method used by the machine.
Step 2: Working of the spinning method.
The spinning process rotates the drum of the washing machine at a very high speed. Due to centrifugal force, water is pushed out from the clothes through the holes in the drum. This process removes a large amount of water quickly and efficiently.
Step 3: Comparison with other options.

• (A) Spinning: Correct. It uses centrifugal force to remove water effectively from clothes.
  
• (B) Bottom drain: Incorrect. Bottom drain only removes water from the washing tub, not directly from the clothes.
  
• (C) Combination of bottom drain and spin: Incorrect. The main effective process of removing water from clothes is spinning itself.
  
• (D) Tumbling: Incorrect. Tumbling mainly helps in washing and mixing clothes, not in extracting water.
  

Step 4: Conclusion.
Therefore, the most effective method of water extraction from clothes in a washing machine is spinning. Final Answer: Spinning.
