Fibers can come from various sources. which of the following is not a common source of fiber among artists?
a. plants
c. minerals
b. animals
d. synthetics

The correct answer is option C, minerals

Reason -

Minerals are chemical components which are very essential for the functioning of the body but they are not considered as sources of fibers. The major minerals required for our body are –  

•Calcium

•Chloride

•Magnesium

•Phosphorus

•Potassium

•Sodium

•Sulfur

These minerals are not trace minerals and thus exists in large amounts in our body.They helps to maintain the regulatory activities in the body. Fibre is a separate essential element required by the body and there are different sources of fiber such as fibrous foods, etc. but minerals do not fulfill the requirement of fibers in our body.
