Answer 2

Both A and R are true but R is not the correct explanation of A.

• The large intestine has three parts and the last (third) part is the rectum which is responsible for storing the faeces or the undigested food before that food is removed out of the body through the anus.
• The large intestine passes electrolytes and water through the undigested food present in it during this period.
• The food is then converted into solid waste i.e faecal matter which can be removed from the body.
• Faecal matter or solid waste can be passed out of the body from time to time through the opening called the anus.

Hence, undigested food is stored in the rectum and is removed out of the body from the anus but it is not the correct reason. So, option b is correct.
