The correct answer to this question is A, (i) and (iii) are the corect statements. Manure is an organic matter, which is mainly made from animal feces. It has many uses including beiing a fertilizer for farming and used for soil amendments. As point (i) indicates, there are many nutrients in manure, including sulfur, calcium, and magnesium.
