Composited manure is formed from

The correct option is "animal refuse and rotted vegetable".

Composting is a biological process in which micro-organisms (such as bacteria and fungi) decompose organic matter under controlled aerobic or anaerobic conditions.
The resulting product is compost or composited manure, which is rich in nutrients and used to improve soil fertility and structure.

To understand why "animal refuse and rotted vegetable" is the most accurate definition among the choices, we can break down the components of composited manure:
1. Animal Refuse: This includes animal dung, urine, and litter from farm animals. These materials are highly rich in nitrogen, phosphorus, and potassium, which are essential nutrients for plant growth.
2. Rotted Vegetable Matter: This refers to agricultural residues, domestic food waste, leaves, and other plant parts that undergo decomposition (rotting). These materials provide organic carbon and help build soil organic matter.

When these two components are mixed and allowed to decompose together, they undergo microbial breakdown to form stable, nutrient-rich composited manure. Therefore, the combination of animal refuse and rotted vegetable matter directly defines the primary inputs used to form compost.
