Question

Determine the correctness or otherwise of the following Assertion [a] and the Reason [r]. 
Assertion [a]: One of the best ways to reduce the amount of solid wastes is to reduce the consumption of raw materials. 
Reason [r]: Solid wastes are seldom generated when raw materials are converted to goods for consumption.

• A. Both [a] and [r] are true and [r] is the correct reason for [a]
• B. Both [a] and [r] are true but [r] is not the correct reason for [a]
• C. Both [a] and [r] are false
• D. [a] is true but [r] is false

Hint:

In waste management, reducing raw material consumption can reduce waste, but waste is also generated during manufacturing and consumption processes.

Answer 1

The Correct Option is D

Assertion [a] is true because reducing the consumption of raw materials directly leads to less waste being generated. However, Reason [r] is false because solid wastes are often generated during the manufacturing and consumption processes, even if raw materials are converted into goods. Final Answer: \[ \boxed{\text{(D) [a] is true but [r] is false}}. \]
