Consider the following statements (A - D) about organic farming:
(A) Utilizes genetically modified crops like Bt cotton.
(B) Uses only naturally produced inputs like compost.
(C) Does not use pesticides and urea.
(D) Produces vegetables rich in vitamins and minerals.
Which of the above statements are correct?

In organic farming, farmers use natural manures, compost, and bio-fertilizers, instead of using chemical fertilizers. Some useful microbes used as bio-fertilizers are bacteria, algae, and fungi. Genetically modified plants are plants which have desirable characters such as resistance to pest, insects, droughts, and salinity organic farming involves the use of natural wild-type plants. Organic farming used to increase agricultural productivity, and maintain sustainable soil productivity, but not to produce particularly vegetables rich in vitamins and minerals. Thus, the correct answer is option C.
