- Spinning
- Bottom drain
- Combination of bottom drain and spin
- Tumbling
Show Solution
The Correct Option is A
Solution and Explanation
Step 1: Understanding the Concept: The efficiency of a washing machine's water extraction cycle determines how much moisture remains in the clothing before drying.
Step 2: Detailed Explanation: 'Spinning' utilizes centrifugal force to push water out of the fabric, but without proper drainage, the water can re-soak the clothes.
'Bottom drain' simply lets water flow out via gravity, which leaves clothes heavily saturated.
A combination of both methods simultaneously spins the clothes to forcefully eject the water and uses the bottom drain to immediately remove that expelled water from the drum.
This synergy ensures maximum water removal without re-contamination.
Step 3: Final Answer: The most effective method is the combination of bottom drain and spin.
