The correct option is B Cotton fabrics absorb water better than nylon fabrics
Cotton and silk are examples of natural fibres whereas polyester, nylon and rayon are examples of synthetic fibres.
Natural fibres are eco-friendly and absorb water better than synthetic fibres.
Synthetic fibres are not eco-friendly but more durable and cheaper compared to natural fibres.
Therefore, polyester is not an eco-friendly fibre and fabrics made of them are cheaper compared to cotton fabrics. Cotton fabrics absorb more water than nylon fabrics. Rayon is more durable than silk.
