The correct options are
B Food rich in fibre content is milk.
C They are digestible substances like cellulose, which is found in plant foods
The two incorrect statements given here are B and C.
Milk produced from animals contains vitamins and minerals, but not fibre. And plants contain compounds like cellulose, hemicellulose, lignin and pectin collectively known as fibre. Dietary fibre or roughage is the indigestible portion of food derived from plants and it adds bulk to the undigested waste material that has to be eliminated from the body. These fibres stretch the intestinal muscles facilitating movement of faecal matter through the large intestine and rectum, thus enabling elimination of waste and preventing constipation.
