Show Answer
Answer:
Correct Answer: C
Solution:
Retting is the process in which plant fibres (jute, hemp, flax) are separated by the activity of micro-organisms.
Plants are immersed in water for a considerable period; during this period they absorb water and get swell.
The water medium becomes rich in harbouring bacteria (Clostridium butyricum) which hydrolyzes the pectic substances of the middle lamella of the fibrous tissue.
