Which of the following activities requires the use of water? 1. Water is strictly prohibited in the generation of electricity. 2. Making fabric from plants. 3. Cleaning utensils. Select the correct answer using the code given below:

Correct Option The correct option is (c) 2 and 3 only. Explanation Water is a fundamental abiotic component of the environment, essential for sustaining life and supporting various economic, industrial, and domestic activities. Its utility spans across agriculture, energy production, manufacturing, and daily household chores. Statement-wise Analysis - Statement 1 is Incorrect: Water is not prohibited in the generation of electricity; rather, it is a critical resource. Hydroelectric power plants generate electricity using the kinetic energy of flowing water. Furthermore, thermal and nuclear power plants utilize vast quantities of water for steam generation and cooling processes. - Statement 2 is Correct: The production of fabric from plants involves several water-intensive processes. For example, retting is a process used for jute and flax where stems are soaked in water to separate fibers. Additionally, the textile industry uses water for washing, bleaching, dyeing, and finishing fabrics. - Statement 3 is Correct: Water is the universal solvent and is indispensable for domestic hygiene. It is the primary agent used for cleaning utensils, washing clothes, and general sanitation. Key Takeaway: Water is a multi-purpose resource essential for hydroelectricity, industrial processes like textile manufacturing, and basic domestic sanitation.
