Correct option is A
The correct answer is Both (A) and (R) are true and (R) is the correct explanation of (A).
• Assertion (A): Polyester clothes dry faster than cotton clothes. This statement is true. Polyester is a synthetic fiber that does not absorb water as readily as cotton, a natural fiber. This means that polyester clothes will dry faster than cotton clothes when they are wet.
• Reasoning (R): Synthetic fibres absorb very less water. This statement is also true. Synthetic fibers, such as polyester, have a hydrophobic nature, which means they repel water. This property makes synthetic fibers less absorbent than natural fibers, such as cotton.
