उत्तर
A is true, but R is false.
Explanation:
The assertion is true because fabric softeners coat fibres with chemicals to make them smooth and reduce static electricity. The reason is false: softeners decrease fabric absorbency rather than increase it, as their chemical coating is water-repellent and prevents fabrics like towels from holding water effectively.
